Hilton has bust-up with Stavros Niarchos

Paris Hilton has been spotted having a bust-up with Stavros Niarchos.

The hotel heiress confirmed this week that her relationship with the Greek shipping heir is back on, but the pair clashed at P Diddy's recent "White Party" in St Tropez.

A source told The Mirror, "Paris was clapping at Diddy's trampoline antics while Stavros was on the other side of the pool glaring at her.

"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!'"
