Trouble in Paris-dise?

Last night, at the most faaabulous bar in Los Angeles, the Abbey, X17 photogs spotted Paris and boyfriend Benji in the midst of a lover's tiff.

Although the two arrived at the bar together (Paris in sister Nicky's pleather pants), after fighting, the couple left the bar separately, but ultimately went home in the same car.

So should we prepare for the breakup of Penji?

"It didn't look like anything major," says our photog. "Just one of those fights between boyfriend and girlfriend at a club. But Paris was obviously upset."

In fact, Benji left the club four minutes before his girlfriend, but ended up simply waiting for her in his car until she decided to join him.

I guess we can all let out a sigh of relief -- doesn't seem like a breakup is imminent after all!
