Actress Amber Heard, who is currently embroiled in a bitter divorce case with her husband Johnny Depp, has been the subject of rumours about a romantic relationship with Tesla's billionaire boss Elon Musk since the couple have been spotted together on numerous occasions. Reports of a possible romantic relationship first surfaced on TMZ. 

According to that report, "Amber Heard -- who's in the throes of a divorce with Johnny Depp -- is spending a lot of time with a guy who makes Johnny look like a pauper -- billionaire extraordinaire Elon Musk ... TMZ has learned. Our sources say Amber has known the Tesla inventor for several years, but in the last few months they've been spending a lot of time together. Just last weekend Amber and her sister were hanging out in Elon's hotel bungalow in Miami.  We're told she had a 1-on-1 dinner at his L.A. house 2 weeks ago. We're told she recently went to Elon's L.A. area office to spend time with him. And we're told he's paid several visits to her home.

No one in Amber's camp is calling it "dating," but we're told the amount of time they spend together has definitely increased. Elon -- who's worth an estimated $12.7 billion -- is also going through a divorce withTalulah. They married, divorced, remarried and she filed for divorce for a second time in March."

Page Six. has also spoken to few people close to heard and they have denied the whole thing "Amber was there with her sister. She has been friends with Elon for four years. She had rented a standard suite at the hotel, and he had a bungalow, a poolside duplex room. He offered Amber and her sister use of his room so they could use the pool and have extra privacy as he was working on a rocket launch." A second source said: "They all happened to be staying at the Delano. The group hung out at the hotel, rather than in public, understandably, due to all the recent press scrutiny."
