With her little sister Hattie in tow, Rachel Bilson attended the world premiere of the new movie "Kit Kittredge: An American Girl" at The Grove in Los Angeles on Saturday (June 14).

The former star of The OC looked to be in high spirits as she smilingly posed on the red carpet before escorting her sis and a friend in for the screening.

In related news, Rachel recently interviewed with Sun Media for a piece related to the DVD release of her hit movie Jumper (which hit stores this past Tuesday), talking about her the usually hush subject of her co-star boyfriend, Hayden Christensen.

“Hayden, he’s a real guy, a guy’s guy, but also sensitive. He’s got both going for him. Strong male characteristics but also vulnerable. You feel for him. It’s a good balance,” Bilson tells.

Explaining her position on doing a Jumper sequel, something Christensen and fellow co-star Jamie Bell have already said yes to, Rachel tells: “Yes! We’re such a good group, first of all. We had such a great time working together. And the concept is so cool and there is so much to explore with it that I think it would be fun."
