Elon Musk has reportedly been courting rumored girlfriend Amber Heard for the past four years.

According to the New York Post's gossip column Page Six, business mogul Elon set his sights on the actress when they co-starred in 2013 movie Machete Kills.

The pair never met on the set of Robert Rodriguez's film, but Page Six have obtained emails allegedly sent by Elon to the director and other acquaintances of Amber's in a bid to meet her.

"If there is a party or event with Amber, I’d be interested in meeting her just out of curiosity,” Elon wrote in one email. "Allegedly, she is a fan of George Orwell and Ayn Rand... most unusual."

He then added in a later message: "I’m not angling for a date. I know she’s in a long-term relationship, but... Amber just seems like an interesting person to meet."

The relationship he was referring to was that of Amber and her now ex-husband Johnny Depp.

She previously sparked rumors she and Tesla Motors visionary Elon were more than just friends by spending an increasing amount of time with the businessman.

Sources told TMZ.com last month (Jul16) Amber had been paying numerous visits to his Los Angeles mansion, while she and her sister Whitney also enjoyed the business tycoon's hospitality in Miami, Florida, where they stayed at his hotel bungalow.

Insiders previously told People.com the actress' relationship with Elon, whom she has known for years, was strictly platonic, but the pair fueled rumors they could be dating when they were seen heading out together in London, England, earlier this month (Aug16).

Amber ended her three-month legal battle with Johnny last week (ends21Aug16), and as part of their official marriage termination agreement she received a hefty payout of $7 million .

Following the settlement, The Danish Girl star announced she would be donating the money to a domestic violence charity and a children's hospital.

Elon, meanwhile, is currently going through his own divorce from actress Talulah Riley.
