Lindsay Lohan has taken to her online blog to slam reports she is to split from girlfriend Samantha Ronson.

The pair, who have been dating since earlier this year, have been dogged with rumours of a break-up following a spate of rows.

The couple was recently spotted arguing in New York, and Britain's The Sun newspaper reported last month that they rowed outside London nightclub Boujis - with Lohan left "in tears" after the incident.

But the Mean Girls actress is sick of the rumours, and is adamant she and Ronson are still together.

She writes on her MySpace blog, "rumors.. Just to clear this up.. Because I have been getting a lot of emails asking me this one question. Samantha Ronson and Lindsay Lohan (me) are Not breaking up," before ending the posting with a smiley face.
