Paris Hilton Makes a Surprise Appearance at Britney’s Birthday Bash!

Tinsel town's finest pop wreck hit the town to celebrate with her BFF and wannabe celebrity, Alli Sims.

As Brit left the Scandinavian Style Mansion party in LA on Saturday, her biggest frenemy, Paris Hilton, followed her out.

But if you're hoping for a reunion between the former BFFs, you might want to brace yourself for some bad news.

While it appeared that Brit and Paris were chilling together, the reunion was short-lived.  

After the two ladies walked out of the club Britney got into her car while Ms. Hilton hopped into another.

Brit's car took off while Paris touched up her makeup and headed back into the club.

But where did Brit head after the party?

We're guessing that she made a run to Starbucks, picked up some fried chicken and called it an early night.

What do you think?
