Demi Moore trying to hook up with Leonardo DiCaprio?

OHMYGOSSIP — Demi Moore really is desperate! American tabloid the National Enquirer claims the actress, 49, is trying to woo back one-time lover Leonardo DiCaprio – but he wants nothing to do with her.

Sources say Demi has been e-mailing and calling Leo, hoping to reignite the spark they shared more than 15 years ago.

“Demi is so lonely and hungry for love,” a source revealed. “After all these years, she’s romanticized what really amounted to just a fling.

“She’s infatuated with the idea of her and Leo becoming Hollywood’s hottest power couple. She’s lonely and facing her 50th birthday this month, so she’s looking to rejuvenate her love life and career.

“Unfortunately for Demi, Leo is giving her the big-time blow off. He won’t even get together with her for coffee! Demi’s dream is to find a young, successful guy who can help elevate her back to her past glory. But she’s barking up the wrong tree with Leo.

“He idolized her when he was in his 20s and fresh off the blockbuster success of Titanic, but now Leo thinks Demi is too old. He doesn’t want to get tangled up in her messy life.”
