Lindsay LohanLindsay Lohan has reportedly shown girlfriend Samantha Ronson that she’s serious about their relationship by agreeing to set up a joint bank account.

The two women have been dating for around a year but since they went public with their romance in September, have had a number of high profile tiffs and arguments, suggesting their relationship is far from settled.

But a source told the Daily Express that Lindsay is “hell-bent” on showing DJ Sam that she’s committed - and is now willing to prove it by sharing her wealth: “Lindsay was reportedly earning £122,000 per episode for her stint on Ugly Betty last year and she’s stashed that into a joint account to show Sam how much she loves her.

“Sam’s very generous to Lindsay. She pays for everything when they go away together and Lindsay wants to show her gratitude by doing this.

“Sam is completely disinterested in shopping and things, whereas Lindsay loves to spend and always says she wants to be as rich as possible. Having a joint account with Sam is a huge step for her.”

The pair are also rumoured to have bought a holiday home together in the Palm Island development in Dubai, after visiting the city last year.
