Lindsay and Sam in Action

Before getting all kissy-kissy at Diddy's party, our favorite female couple dined together at Baoli Restaurant.

Lindsay, sporting the Lauren Conrad side braid 'do, seemed a bit tense as she left the restaurant, telling one of her handlers to "calm down"!

But it was all smiles when she got into the car with Sam, giggling at the photogs who asked Lindsay to "give us a kiss" (which she apparently did later!), and leading Sam firmly by the hand into Diddy's party!

Course, Sam wasn't the only one Lindsay was kissing at the party - check out the pix after the jump!

And we've added even more Rondsay pix to the gallery, so click through for more of Lindsay and Samantha's night together!
