Actress Amber Heard has reportedly split up from her boyfriend Elon Musk.

Heard, 31, is apparently "devastated" after tech tycoon Musk ended their year-long romance. Last night a source told the Daily Mail: "It's all over between Amber and Elon and she's devastated. It was his decision.

"He ended it a week ago. He'd heard certain things about her behaviour that didn't sit well with him.

"Amber can be very manipulative and selfish. Elon's back in LA while she's licking her wounds in Australia."

Musk, 46, worth a reported £12 billion, made his first fortune as co-founder of online service PayPal.

The creator of electric car giant Tesla and private space company SpaceX, he was spotted with Heard in Australia in April where she is filming the £100 million superhero movie Aquaman and was said to have put his private jet at her disposal.

Their romance began shortly after South African-born Musk divorced British actress Talulah Riley for a second time last year.

Heard was still recovering from what she called a "toxic" split with Depp.

Her lawyers accused the actor of hitting her and subjecting her to repeated abuse throughout their 15-month marriage, claims he denied.

Heard received £5.3 million from the divorce which she vowed to give to charity.

A spokesman for Musk, who has five sons from his first marriage to Canadian writer Justine Musk, said: "We don't have any comment on this story."
