Get a Room!

Fireworks were not just going off in the sky over the 4th of July, they were also exploding on the beach. Kristin Cavallari and Jamie Lynn Sigler were all over their men, in a very public "get a room" sort of way.

Kristin Cavallari and boyfriend Brody Jenner just couldn't get enough of each other in Malibu on the 4th. The two were guests at the Smashbox Cosmetics Independence Day party held on the beach at the Polaroid Beach House.

Check out Jamie Lynn Sigler's Beach PDA.

Jamie Lynn Sigler let her hands do some exploring on new boyfriend Scott Sartiano's backside in Malibu. In between all the touching and feeling, the two lovebirds also spent some time with new couple Jim Carrey and Jenny McCarthy.
