All the usual Hills suspects were out in LA last night to celebrate Stephanie Pratt's birthday party at Boulevard 3. Heidi and Spencer came bearing flowers and balloons, while LC probably wasn't loving life while at the party with her enemies. Of course, the cameras were around the whole time, so we'll be seeing exactly what went down inside when the episode airs in a few weeks time. Thankfully for Lauren in her new extensions, she doesn't have to party with Heidi and Spencer again tomorrow — they politely declined their invite to the White House on Saturday. Don't fret though (wink), I'm sure we'll all know how they spend their weekend anyway.
