Lindsay Lohan has set up a joint bank account with her girlfriend Samantha Ronson.

The Mean Girls actress is determined to show her commitment to her DJ lover by depositing huge sums of her cash for their life together.

“Lindsay was reportedly earning $244,000 per episode for her stint on ‘Ugly Betty’ last year and she’s put that into a joint account to show Samantha how much she loves her,” a source revealed to Britain’s Daily Express on Sunday.

“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,” the insider adds.

“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.”
