“I definitely was not having an affair with Amber while she was married to Johnny, this is totally false,” the Tesla mogul told the New York Times of cheating claims made during Depp’s explosive libel trial in the UK.

Musk, a 49-year-old father of six, laughed when asked about other claims in legal docs that he had a threesome with Heard, 34, and model Cara Delevingne, 27, in Depp’s LA penthouse.

“We did not have the threesome, you know. So I think people think these things are generally more salacious than they are,” he told The Times.

Insisting that he only started dating now-ex Heard after she split from Depp, Musk suggested during an hour-long phone interview that the warring exes “bury the hatchet and move on.”

Musk — who is worth more than $66 billion, according to Forbes — again chuckled when The Times asked about court revelations that Depp had dubbed him “Mollusk” in a slur against his feared love rival.

“Well, yeah, I hope he recovers from this situation,” Musk told the paper.

He had a far more unexpected response when asked about text messages the “Pirates of the Caribbean” star had sent allegedly threatening to “slice” off the mogul’s “d–k.”

“If Johnny wants a cage fight, just let me know,” Musk told The Times, again giggling.

Musk called current partner Grimes — who recently gave birth to their baby son X Æ A-Xii — “pretty special.”

“She’s one of the most unusual people I’ve ever met,” he said of the 32-year-old singer, whose real name is Claire Boucher.

“We’ve had this debate of ‘Are you more crazy than me or am I more crazy than you?’” he told the paper.

The singer “has a much bigger role” raising their son because “babies are just eating and pooping machines,” Musk told the Times.

“Right now there’s not much I can do … When the kid gets older, there will be more of a role for me,” he said.
