New BFF Alert!

Lauren Conrad and Audrina Patridge appeared to have found a replacement Heidi last week when they were spotted lunching with Nicole Richie in L.A. But then Lauren and Nic ditched the third wheel and dined as a duo on Sunday. "The friends greeted each other warmly," People reports, "and as they sat and pored over the menu, mom-to-be Richie was especially cautious about what she was eating (she eventually settled on green salad and a salmon tempura roll)." Perhaps a new reality show is in our midst -- The Simple Hills?!
