Rachel Bilson stays in shape by dancing.
The 31-year-old actress prefers dancing to regular exercise and credits it with helping her to keep fit.
Speaking at the BlackBerry Z10 Smartphone launch party at Cecconi's Restaurant in Los Angeles on Wednesday (20.03.13), she told BANG Showbiz: ''I love dancing, it's such a great way to stay in shape.''
Rachel also revealed she loves to take fashion risks, even if they don't always work out.
She explained: ''I don't like to say no when it comes to fashion. My motto is try it once and if it doesn't work don't do it again. Right now I love plaid, I have plaid everything.''
Meanwhile, Chloe Moretz, 16, also attended the party and said she loved working with Jim Carrey on the upcoming movie 'Kick Ass 2' but didn't try to turn the tables on the funnyman.
She said: ''I loved working with Jim, he's so great. We didn't play any practical jokes on him though.''
Chloe, who was joined by her brother Trevor at the event, later tweeted: ''Having the best time at the Blackberry Z10 launch event #blackberry10! (sic)''
Rachel and Chloe were joined at the party by stars including Christina Ricci, Rosie Huntington- Whiteley, Pia Toscana and Josh Duhamel.
