Jared Leto has been linked to many Hollywood stars lately, most recently, Miley Cyrus.

A source tells Us Weekly that the two are "hooking up."

"She stayed over his house in L.A. in early February," the source said.

It happened weeks after the pair were pictured talking at a pre-Grammys party thrown by Clive Davis, which took place on Jan. 25 at the Beverly Hilton in Los Angeles. The two actor/singers have known each for a while, but recently became more intimate.

"They like to have a good time, they love to talk about art and music - and they're both comfortable with nudity!"

The source adds that there isn't a relationship forming, as Leto does not "do girlfriends." The 30 Seconds to Mars singer and Oscar nominee has also recently been tied to "12 Years a Slave" star Lupita Nyong'o.

Reports said they were on a date after a New York Fashion Week show, and the two have been friendly on their road to the Oscars. A picture at the Screen Actors Guild Awards showed the two talking closely, posed in a similar position as he and Cyrus were. Leto was also said to have been flirting with "Game of Thrones" starlet Emilia Clarke at the same awards show during an interview with E! reporter Giuliana Rancic.

Similarly, it doesn't seem Cyrus wants to be in a relationship.

She told W that she is "not trying to jump into a relationship" after splitting from fiancé Liam Hemsworth last year, said the NY Daily News.

Neither celebrity has spoken up about the rumor, but it seems Leto is having quite the busy month. He was also spotted trying to cozy up to Taylor Swift at the InStyle and Warner Bros. Golden Globes after party.
