Celebrity Fashion Face-Off: Rachel Bilson vs. Leighton Meester

From their acting roles to good looks and easy-going fashions, Rachel Bilson and Leighton Meester are both THG favorites. But whose summer style is best?

Rachel, who just ended her engagement with Hayden Christensen, shouldn't have any trouble landing a new guy to fill his shoes in these new jean shorts.

Appropriately, they're Paige's "Jimmy Jimmy" cuffed "boyfriend" style!

Meanwhile, Gossip Girl star Leighton has been showing some leg in Anlo's frayed "Cammie" shorts from Paris to California to New York and back again.

So cute, both of them ... but who wears the look better? Vote below!
