Kat Dennings (24) vs Natalie Portman (29) - 2010 Flashback Fight

"Okay, let's hold it there. Natalie, you're free for now. Everyone else, let's reset and do it again."
Natalie Portman smiled and absentmindedly brushed her hair back as she walked off the set, giving a quick wave to Chris Hemsworth as she went. The bustle of the crew died down as she rounded a corner toward the cast area. As she'd expected, she found Kat Dennings laying out in the sun in a tank top and shorts, her laptop on her lap.
"Hey, Kat," Natalie said, sitting down on the lounger next to her.
"Hey," Kat replied, her eyes still on her screen. "Sup?"
"Got a break from filming," she said. "They've got a bunch of Thor stuff to do, so I think we're good for a while."
"Uh-huh."
"Sorry, am I interrupting something important?" Natalie asked with a smile. She leaned over and looked at the screen. "What are you looking at there?"
Kat looked up suddenly and a sheepish grin appeared on her face.
"I sorta stumbled on it," she said. "You know, I was just Googling myself, and
this came up..."
"Celebrity catfights?" Natalie read, cocking her head slightly. She locked eyes with Kat, who shrugged.
"It's like, uh... I'm only just discovering it myself, you know?"
"Please, enlighten me with you new-found knowledge."
"It's some kind of fan thing, I think," Kat explained. "People pit celebrities against each other, you know - actors, singers, models, whatever - see who'd win in a fight. Sometimes they do polls, sometimes they just discuss it... a couple of 'em even write stories."
"Right..." Natalie scrolled down the page, glancing at the names. "So how are we doing? Getting a lot of wins?"
"There's only one with me in it, that's how I ended up on this site," Kat said. "That was a win, though. You, uh... your record's not so great."
Natalie sat back, an expression of mock-offence on her face.
"What, people don't think I'm tough?"
"They seem to think you're, uh... small. The bigger girls tend to win more."
"That's ridiculous!" Natalie said. She flashed another grin and grabbed Kat's arm. "Come on, you and me, right now."
"What?" Kat put a hand over her mouth to hold back a laugh. "No offence, Nat, but I don't want to hurt you."
"You have my permission," Natalie replied. She whipped out a tie and put her hair back into a ponytail. "Come on, we've got time, no-one is around. Show me what you've got."
"Okay," Kat said with a smile. "But don't be surprised if you find yourself pinned down under me."
The girls moved away from the loungers into a more open space. Kat went down on her knees, and Natalie followed her example.
"So I guess first to give up loses?" Kat said. Natalie shrugged and nodded. She shuffled forward on her knees.
"Okay... good luck, then." Kat launched herself forward and wrapped her arms around Natalie's body, pinning her arms to her side. The force of it pushed her onto her back, and Kat quickly laid on top of her, keeping a tight grip.
"Gotcha!" she exclaimed triumphantly. Natalie wriggled beneath her, but Kat held firm.
"Okay..." she muttered. Kat grinned and released her grip, instead grabbing Natalie's wrists and pinning them by her head.
"There we go," she said. "I'm not one to say 'I told you so', but-"
Kat's words were cut off as Natalie pulled her legs up and snapped them around the bigger girl's head. Kat let out a grunt of shock and instantly let go of Natalie's wrists, instead grabbing at her legs. Natalie moved quickly, bending her right leg behind Kat's head and pulling her deeper between her thighs.
"But what?" she asked with a smirk. She pulled her leg tighter, and with her free hand grabbed Kat by the back of the head.
"Okay, now hold on tight, I'm gonna roll us over."
With a grunt, she threw her weight sideways, rolling both her and Kat over to leave the bigger girl on her back. Natalie settled back, sitting on her chest, her legs still around her head. She reached down and brushed Kat's hair off her face.
"Jeez, Nat," Kat gasped. "How do you know how to do this?"
"I told you I was strong, Kat," Natalie replied. "Or I implied it, anyway. Look, tell you what, I'll give you another chance."
She deftly untangled her legs from around Kat's head and stood up, offering her hand as she did. Kat accepted, and Natalie pulled her to her feet.
"Okay, you're not a pushover," Kat said, going back to her knees. "But neither am I."
Again, Kat lunged forward, this time grabbing Natalie around the legs and tackling her to the ground again. She moved forward, straddling the smaller girl's legs.
"You good there?" Natalie asked. Kat grinned.
"I've got your legs, girl. You're not gonna get me like that again."
Natalie smiled back at her.
"So what, are you gonna try and pin me now?"
"Giving up so soon?"
Kat shuffled forward to sit on Natalie's thighs, grabbing for her wrists. Natalie sat up and quickly wrapped her arms around Kat's head, pulling her face into her chest.
"Oh, come on," Kat growled. Natalie grinned.
"I'm sorry, but you are making this too easy right now."
"I'm still on top of you!" Kat protested.
"Please."
Natalie bucked her body and once again rolled the pair of them over, leaving Kat on her back. She quickly readjusted her position to straddle Kat's legs instead.
"Come on!" Kat gasped. She pushed in vain at Natalie's shoulders, but Natalie held strong.
"You're not my first," Natalie said. "I always try to get in some fights with my co-stars."
She unwrapped her arms from around Kat's head and swiveled herself to lay across her body instead. Kat barely had time to react before Natalie's legs locked around her right arm, and her own arms around Kat's left.
"It started with Keira Knightly, when I was doing Star Wars - she was scrappy, but I had a few years on her and she never really stood a chance."
She shuffled slightly, pushing her waist against Kat's neck and pushing her head back.
"I don't think I'm faring much better," Kat gasped.
"Scarlett Johansson, she was a tough one," Natalie continued, ignoring her. "I beat her a few times, she beat me a few. Good fighter."
Kat kicked her legs uselessly.
"Then last year, I did Black Swan with Mila Kunis," Natalie said. She turned her head to look at Kat. "Did you ever see that one?"
"Saw it on a plane once," Kat replied weakly.
"So obviously we were both in great shape for that. She kicked my ass most of the time. And her favorite move was this one..."
With a sly grin, Natalie yanked up her top and pulled Kat's face against her belly, smothering her. She held her for ten seconds before releasing her.
"Jesus Christ," Kat gasped, her face red.
"I know, right?" Natalie laughed. "Got me every time. Give up yet?"
"Yeah," Kat replied. "I give up. You win."
"Even though I'm small?"
"Even though you're small."
Natalie smiled and untangled herself from Kat. The bigger girl stayed lying on her back, taking a few deep breaths. Natalie leaned over her.
"You okay?"
"Yeah, I'll be fine. Good fight."
"Oh, no, sorry, we're not done yet."
Natalie swung a leg over Kat's body, facing her feet as she straddled her chest. Kat groaned and didn't bother trying to resist, still to exhausted to fight back.
"Nothing personal, you know," Natalie explained, pulling a mobile out of her pocket. "But I told the girls I'd let them know how it went, so..."
She held the phone high above her and began recording with a smile on her face.
"Hey guys! I'm here in New Mexico to film Thor, and guess who I just beat up?" She moved the camera to focus on Kat's face.
"Tell them who you are, honey."
"I'm... I'm Kat Dennings."
Natalie moved the focus back to her own face and nodded.
"Kat didn't know I was a fighter. Now, I'm sure she'll want another go soon, but for now, I'll take my victory. This'll be you next time, Mila."
Natalie leaned over and placed the phone on the ground, giving it a wider angle on the scene. That done, she shuffled herself backward until her denim-clad ass was perched firmly on Kat's face.
Kat immediately began struggling, and she grabbed at Natalie's thighs to try and pull her off, but the smaller girl managed to keep her balance, and kept her eyes firmly locked on her phone's camera. Slowly, Kat's struggles stoppled, and Natalie sat up.
"Next time, Mila," she said firmly, before ending the recording.
