Lauren Conrad's never been known for her hard-partying lifestyle, but last weekend she kicked it into high gear for her cousin's bachelorette. And before you get all judgmental and "What would her mom think?" you might wanna take a look at these mother-daughter pix from party central! Yep, turns out Kathy Conrad (that's Mrs. C to you) was totes along for the ride, joining the girls for dinner/drinks at the club on Saturday and a fun-filled day at the beach on Sunday. What, haven't you ever heard of a girls' weekend before?
