New York, Mar 23 : Lindsay Lohan is believed to be having trouble in her relationship with Samantha Ronson because of her massive overspending.

According to friends, the `Mean Girls' star's overspending is out of control, and it's putting additional strain on the actress' already volatile relationship.

"Lindsay is spending like crazy! She's living on credit right now. She has no cash. The problem is, the money being spent is mostly Sam's because Lindsay doesn't really have any of her own at the moment; she's really taken on the `man' role in their romance," the New York Daily News quoted a pal, as saying.

"Sam really thinks Lindsay needs to learn how to become a recessionista and manage her money better," the pal added.

Another pal said. "Lindsay's money situation has never been great, but it's only gotten worse over the last month. For every dollar she makes, she spends double.

"Her personal appearance fees are literally the only thing keeping her afloat. But here's the rub: Because of her explosive relationship with Sam, she's unable to get the type of cash she's used to. The negative press and constant appearance cancellations are hurting her pocketbook," the pal added.

A rep for Lohan said: "I know nothing of her spending. But she has her own money." (ANI)
