Insiders say she's got the hots for music producer JR after she enlisted him to work on her new album in a last-ditch bid to get her struggling music career off the ground, NW reports.

Sources say that as soon as Lindsay teamed up with JR, she decided he would be her next celebrity conquest — because she's desperate to land herself a sugar daddy after blowing most of her $34 million fortune.

"She's dying for some rich guy to take care of her," says a pal.

While Lindsay's earned millions from her movie career, her shopping and partying addictions have reportedly left her struggling to stay afloat financially.

"It's sad," says a friend of the actress. "This kind of thing should not happen to a major movie star."

Determined to land her man, the 21-year-old starlet was spotted turning on the charm in a very public flirt-fest with the producer. In between recording sessions, Lindsay and JR, 32, took their romance to the streets as the couple shared cigarettes and a series of whispered conversations outside an LA music studio.
