Lindsay Lohan and Paris Hilton clash at Timbaland's pre-Grammy party

Lindsay Lohan and Paris Hilton had a huge bust-up at Timbaland's pre-Grammy party Saturday, it has been revealed.

Lohan and Hilton - who used to be close friends, both attended the producer's bash at Hollywood nightclub Avalon - and were not happy to see each other.

Sources claim Lindsay pointed at Paris and said: "What the hell is that b***h doing here? I didn't know she was on the list."

To which Paris angrily replied: "F**k off you b***h."

Lindsay and Paris were both hoping to convince Timbaland - who has worked with Justin Timberlake, Nelly Furtado and 50 Cent - to revive their fledging music careers.

A source told Britain's Daily Mirror newspaper: "Both saw the party as an ideal way of getting him on side - but they didn't count on the other being there."

Lindsay - whose last single 'I Live for the Day' bombed after receiving no radio airplay - arrived at the bash first and immediately made a beeline for the hit producer.

However, Timbaland ignored her and when Paris showed up - the socialite took a seat directly opposite Lindsay, which was closer to the music mogul.
