Janice Dickinson says Katie Price looks like a "beached tuna" and has no chance of making it in America.
The former supermodel is not a fan of the British TV star and was even less impressed with her when she unexpectedly ran into her at an airport.
In an interview with Britain's Star magazine, Janice said: "She came over to me in an airport once, shouting, 'Janice! Janice!' and I thought, 'Who is this sycophant?' She was like, 'I'm Katie Price aka Jordan.' She was going on about her Botox, teeth and her lips. And I said, 'Well, honey, my lips are real!' I thought she looked like a beached tuna."
The 56-year-old star has also scoffed at Katie's plans to break the US because she believes she has no discernible talent that would appeal to American audiences.
She said: "Loads of people don't know who Katie Price is in America. She could not act her way out of a paper bag - her lips would get in the way and those massive t**s. If she went swimming they'd sink because they look like concrete."
Katie has claimed a movie biopic based on her autobiographies is being made in Hollywood.
She said: "My movie is definitely on - I'd love Megan Fox to play me, she's stunning. As for the rest of the cast, I'm not too worried. As long as they're good-looking."
Katie released her first autobiography, 'Being Jordan' in May 2004 and subsequent instalments 'Jordan: A Whole New World', 'Pushed to the Limit' and 'You Only Live Once' in April 2006, February 2008 and October 2010 respectively.
