Lindsay Lohan and girlfriend Samantha Ronson are undergoing counselling in a bid to save their troubled relationship, according to U.S. reports.

The Mean Girls star has been romantically linked to the DJ since they were spotted kissing and cuddling at a party in Cannes, France earlier this year.

And the actress declared her love for Ronson in a recent magazine interview, saying, "She's a wonderful person and I love her very much."

But now the pair are "are fighting like cats and dogs," a source tells New York gossip column PageSix.com.

"They fight every day, screaming, crying and yelling at each other.

"Sam and Lindsay are still very much together and very much in love, but 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 reports come after the couple was recently spotted rowing in the Big Apple and Britain's The Sun newspaper reported this week (17begNov08) that the pair argued outside London nightclub Boujis - leaving Lohan "in tears".

The source adds, "Lindsay is high-maintenance and a lot to deal with. And Sam has always dealt with her. But it isn't easy.
