Paris HiltonFormer partying pals Paris Hilton and Lindsay Lohan were reportedly far from happy to see each other at a pre-Grammys event on Saturday night.

A source told the Mirror that Lindsay was the first to arrive at Timbaland’s party at Avalon in Hollywood and repeatedly tried to catch the producer’s attention before Paris arrived surrounded by a large entourage and took a seat opposite Lindsay - and far closer to the man of the moment.

The source explained: “Both of them want to work with Timbaland to revive their faltering music careers.”

“Both saw the party as an ideal way of getting him on side - but they didn’t count on the other being there.”

The onlooker reports Lindsay pointed at Paris and shouted: “What the hell is that bitch doing here? I didn’t know she was on the list.”

Paris then retorted with “F*** off you bitch.”

Not to be put off her game, Lindsay is said to have started climbing over a sofa to talk to Timbaland but Paris took a shorter route over a barrier and got to him first.

But Timbaland wasn’t impressed with the women’s antics: according to the newspaper, he gave the pair a blank stare then walked off.
