Although she already celebrated her 21st birthday with a Vegas bash over a week ago, Kristin Cavallari felt the urge to rejoice with another shindig in her honor.
After attending the premiere of "Cloverfield", Cavallari headed over to the Stone Rose Lounge in West Hollywood, California.
There, the former Laguna Beach star was joined by the likes of Paris Hilton and Cisco Adler, partying well into the night.
As reported previously by Gossip Girls, Kristin officially turned 21 on January 5th, partying at Luxor's LAX nightclub.
"My first official drink was Grey Goose and soda," she said. "It's really exciting. I can go to the clubs and not worry about anything."
