The cracks are beginning to show in Lindsay Lohan and Samantha Ronson's relationship with the couple having yet another public row. 

The couple - who were partying at the extravagant launch of a hotel in Dubai - reportedly came to blows over Sam's long set.

A source tells the Daily Mail, "At one stage Lindsay approached Sam in the DJ booth and screamed at her, 'How many more songs? How long is it going to take for you to pack up?"'.

And the screaming matches seem to be coming thick and fast.

A source tells Page Six, "Lindsay and Sam are fighting like cats and dogs. 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.

The source adds, "She deals with Lindsay every day. And every day for Sam means questioning, "Is this worth it?"'

The couple - who stayed in separate rooms at the plush Apex Hotel during their Dubai visit - are rumoured to be seeking couples counselling.
