(Cover) - EN Star Style - Rachel Bilson is more interested in keeping in touch with Karl Lagerfeld then her hunky male co-star in the new Magnum campaign.

The stunning actress was shot by Chanel creative director Karl in a commercial for ice-cream brand Magnum.

She stars alongside handsome male model Baptiste Giabiconi in the adverts, although she was far more excited about collaborating with Karl.

"Apparently he's a very big model," she told NY Mag of Baptiste. "I recognised him once I met him from shows and walking he's always with Karl. He was really sweet too obviously a very good-looking person - [but] I'm more interested in keeping in touch with Karl!

The star was particularly thrilled as she managed to nab the fashion gurus Chanel notepad. Rachel is a massive fan of the iconic French fashion house and is regularly in the front row at their catwalk shows.

He was so funny he was writing down something on this Chanel notepad, and he was like, 'Do you want it?' And I took it so fast he laughed at me, so I got a Chanel notepad from Karl. And my friend was with me she was like, 'Can I at least have a piece of paper from it?' I was like, 'Absolutely not,'" laughed Rachel. (C) Cover Media
