"Lindsay was reportedly earning 122,000 pounds 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," the Daily Express quoted a source as saying.
"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 source added.
The couple had allegedly bought a luxury apartment in Dubai, and friends predict tying the knot maybe their next step.
