Lindsay Lohan and Samantha Ronson are rumoured to be on the rocks yet again after a series of bust-ups over the New Year period.

After coming to blows at club Mansion in Miami in full view of the crowds (see the video below), the warring couple moved on to another location to continue their lover's tiff.

The fight reportedly spilled out into a back alley where Lindsay allegedly began screaming, "When I storm off, you are supposed to follow me!"

The next round apparently kicked off back at their hotel where, according to blogger Perez Hilton, several sources heard, "crashing sounds and screaming".

An eyewitness said, "They were punching each other - it was bad. And they were doing this in front of all of us. It was scary."

Despite the New Years fireworks, the pair appeared to have patched things up by the time they left for L.A.

A spokeswoman for Lindsay said, "There was an argument. I don't know the details, but they left for Los Angeles together and it's fine."
