America’s most eligible bachelor, billionaire Elon Musk, is on the prowl following his split from Amber Heard in August, sources tells Page Six.

While Heard has been spotted making out recently with a studly Kiwi stuntman, as ­exclusively revealed by Page Six, Musk has been making tongues wag with speculation over his current love life.

The Tesla billionaire flew down to Rio this past week for Guy Oseary’s renewal of his wedding vows. And a source said one reason for Musk’s arrival in town was to pursue “Fifty Shades of Grey” star Dakota Johnson. Said a source, “He’s definitely on the prowl and flew down to see Dakota.”

But a rep for Musk tells us, “Elon attended Guy’s wedding because they’re friends and Guy invited him. He knows Dakota and obviously wouldn’t need to fly to Brazil if he wanted to see her. He left the wedding right after the speeches were done in order to fly back to the Tesla Gigafactory for critical work on Model 3 production.”

While at the factory, Musk posted a widely circulated Instagram pic of himself on its roof, roasting marshmallows and singing Johnny Cash’s “Ring of Fire.”

On Thursday, Musk turned up at Simon Hammerstein’s Garden of Wonder by Perrier-Jouët in LA with a group including model Jessica Hart. “Elon and Jessica sat next to other at a private table and were drinking Champagne,” says a spy. “They were sitting very close and chatting off to one side.”

Hart split from longtime boyfriend Stavros Niarchos III in July. We’re told Musk seemed in a good mood, but was trying to be incognito and didn’t want his photos taken.

The rep for Musk tells us, “Jessica and Elon were part of a large group that briefly attended that party. However, there was nothing romantic or ‘cozy,’ and they hadn’t even met before last night. Definitely not a date.”

Heard and Musk split amicably.

Also at the event were Usher and Alessandra Ambrosio.
