Lindsay Lohan and Samantha Ronson have denied reports they were having counseling to repair their relationship following a series of rows.

A source said: "They are fighting like cats and dogs. Drama just seems to follow Lindsay, and Sam hates it. She deals with Lindsay every day. And every day for Sam means questioning, 'Is this worth it?'"

The pair reportedly had a physical fight in London recently after Samantha became jealous of Lindsay flirting with her ex-boyfriend, model Calum Best.

A source said: "Calum went up to Lindsay on the dancefloor. Lindsay was lapping up the attention, having a laugh - and a flirt. But Sam saw them and went ballistic."

"She marched over and started pushing the pair, demanding to know what they were doing. Then it erupted into a catfight, with Sam and Lindsay swearing and screaming like banshees."

The "Mean Girls" star was later seen sobbing outside their hotel in the early hours of the morning.
