The start of the rivalry....Our two protagonists first met when on a shoot for British lads' mag Nuts. Hollie was in the foulest mood - she was not given top-billing! That was awarded Peta, the longer serving model and perceived by the mag's editors as the more popular. "It's soooo not fair!" she moaned to anyone who'd listen. "Who does she think she is anyway?"
Peta retained a dignified silence. Instead letting the pictures do the talking. Here they are, with Hollie on the left and Peta centre, as befits the top-girl:

The barbed comments continued all the day of the shoot. Hollie eventually not caring when Peta heard her badmouthing her rival rather than making comments behind her back. It came to head after the final series of shots with Hollie, Peta and two other girls:

Peta exploded: "Listen you dumb shortass, just shut the fuck up will you? I don't have a problem with you but I'm getting there!"
"What do you mean shortass?" shouted back Hollie, fuming. She'd not expected a direct challenge from the bigger girl. "I'm 5'6"!".
"Yeah? Really? Don't make me laugh!" chuckled Peta. I saw your Miss Trafford entry and knew you'd been lying - you're 5'4" or 5'5" tops!" and the other girls laughed, knowing it was true. Peta walked up to Hollie and stood toe to toe with her, and the difference was clear for all to see. Hollie was barely looking at her nose! "Want to make something more of it, missy?" she laughed, knowing she was intimidating the shorter girl, her 5'9" frame challenging her would-be rival.
