Ever since they co-starred in “Jumper,” we’ve loved seeing this duo together. And yesterday (October 9), Rachel Bilson and Hayden Christensen were spotted smooching on the set of a Lacoste commercial.

The “Last Kiss” hottie was all about getting a few more smooches from her “Shattered Glass” boyfriend as they relaxed in between takes, also taking time to play with her canine companion Thurmen Murmen.

Mr. Christensen looked preppy-yet-hunky in a blue polo-style top, charcoal jeans, and black shoes (he also sported a funky harness-looking vest at times), while Miss Bilson cutened things up with a black and grey printed short-sleeved dress with knee-high black leather boots.

Rachel just finished up promoting her new line of clothing with DKNY Jeans. Recently, she told press, “Everything is under $100 and I always say fashion doesn’t have to cost that much money, which is why I thought of it as a really good line to associate with and I just think that they are very relatable for young girls.”

She continued, “It’s important to like what you come up with, I think. And it’s definitely a reflection of myself and favorite pieces and you know just represents my dream closet.”
