A source told the Mail On Sunday: "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."

Elon made his first millions as co-founder of online payment service PalPal and is CEO of electric car giant Tesla.

She seemed happy with Elon, and confirmed their romance back in April after posting a snap of them in Australia with the businessman sporting a lipstick mark on his cheek.

Captioning the picture "cheeky", Amber also draped her arm over the businessman's shoulder while pouting provocatively at the camera.

Her beau posted a similar picture, captioning his snap: "Having moo moo at Moo Moo Gold Coast with @AmberHeard."
