Lindsay Lohan accuses Samantha Ronson of spitting in her face

Lindsay Lohan has accused ex-girlfriend Samantha Ronson of spitting in her face.

According to the troubled actress, she was at a pal's party last night (20.04.10) when the DJ – who Lindsay dated on and off for 18 months – committed the disgusting act.

She tweeted: "Fun @coachella but tonight @ my friernds bday party, @samantharonson spit in my face and left w/ @mileycyrus's ex. (sic)"

Before hooking up with Liam Hemsworth, Miley was in a relationship with model Justin Gaston for nine months and her boyfriend before that was Nick Jonas.

Samantha – the sister of music producer Mark Ronson - seemingly hit back at Lindsay's allegation on her own twitter page.

In a posting made an hour after Lindsay's, she wrote: "Guess what didn't happen tonight."

Meanwhile, Lindsay's mother Dina has denied her daughter owes $600,000 in credit card debts.

It was reported earlier this week the 'Mean Girls' star has racked up the huge bill, but Dina insists Lindsay's financial matters are all in order.

She told RadarOnline.com: "She is not going into credit card debt. Absolutely not. And her business managers... I actually am in contact with them every day. And you know Lindsay will spend money but she has people that run what she does. Lindsay doesn't really pay her bills. Someone else does, so they wouldn't let her do that.

"And in the interim, you know, a bill may be a little late or not, you know, but that's pretty normal. That happens to me, that happens to everyone. Lindsay isn't in charge of her finances, other people are and we are keeping a close eye on the people who are managing her."
