Paris Hilton left no doubt last night that she and football star Matt Leinhart have something going on that's more than just a friendship. Although the two arrived and left separately from the Xbox 360 E3 party at the Roosevelt Hotel in Hollywood, they were definitely together inside the bash. "Paris and Matt were all over each other," a party-goer tells "The Insider"'s Marc Malkin. "It was extreme PDA."
Rumors began swirling that the hotel heiress was dating the former USC quarterback shortly after she and Greek billionaire Stavros Niarchos III split up. Hilton and Leinart were recently photographed shopping at the Grove mall in L.A.
