Lohan denies Ronson split - again

Lindsay Lohan has once again been forced to hit back at reports she has split from Samantha Ronson - after she turned up to promotional duties without the DJ in tow.

The star and her partner have been dogged by break-up rumours throughout their turbulent and highly publicised romance.

In February, the couple were reported to have split after they failed to commit to hosting duties at a St. Valentine's Day party in Florida. The story prompted the actress to address the rumours - telling the press their relationship is "fine".

And last month the duo's love affair was purported to be in trouble again after a furious bust-up at the DJ's home resulted in a smashed window.

Now, Lohan has taken time to insist she is still very much with her girlfriend - as she attended the launch of a new fake-tan product without Ronson by her side.

Lohan told E! Online: "Those rumours aren't true. We aren't broken up."

And a source told the website that Lohan and Ronson are spending time with the other people in their lives - like any normal couple.

The insider explained: "They've been spending time with their families and working. It's normal and healthy to do that. That doesn't mean they broke up!"
