KANGAROO JACK star Jerry O'connell was so nervous when he initially landed his gig as the face of Perry Ellis clothing, he asked his girlfriend Rebecca Romijn for modelling tips.

O'Connell, 31, graces billboard and magazines in ads for the fashion giant, but his 32-year-old ex-model lover helped give him the confidence boost he needed to take on the project.

He says, "I was nervous (about posing) at first, but because Rebecca used to model, she was like, 'Don't be afraid - it'll be cool. Just make sure you smile.'

"We actually practiced!"
