Are Paris and Stavros on the outs ALREADY?!

Well, this IS Paris we're talking about here. Any relationship that lasts longer than a few weeks is really something for her. MSN reports this:
So much for Paris Hilton’s renewed romance with shipping heir Stavros Niarchos.

Just days ago, the partying heiress was back in the arms of her ex-beau, declaring, “We’re together now here, we love each other.” Now, it looks like the two have split again. The two were at P. Diddy’s white party in Saint Tropez, and the shipping heir stormed out after Hilton accused him of not trusting her, according to reports.

“Paris was clapping at Diddy’s trampoline antics while Stavros was on the other side of the pool, glaring at her,” a source told the London Mirror. “He began texting Paris to come over, but she refused, sending him harsh messages on her diamante-covered Blackberry. Eventually, she stormed over and yelled, ‘Don’t you trust me? Get over it!” Stavros reportedly stormed off while Paris continued to party with Diddy until 6 a.m.
