Celebrity News:

After months out of the limelight, former "Laguna Beach" star Kristin Cavallari ('memba her?!) resurfaced in Beverly Hills on Tuesday. Robertson Blvd. hasn't been the same without her!

Lauren Conrad's pre-Heidi Montag nemesis was snapped heading to her dirty BMW, when a photog stumped Kristin by asking what her favorite Christmas carol was. How about the one that goes, "On the first day of Christmas, my true love gave to me ... a car wash!"

In her defense, if your borefriend was hunkalicious Nick Zano -- you'd stay home and forget to wash your things too!
