Lupita Nyong'o, out, Miley Cyrus, in? The latest red-hot dating rumor about Miley is that she is hooking up with Best Supporting Actor Academy Award frontrunner and 30 Seconds to Mars frontman Jared Leto.

Just last week, rumors that Leto was dating fellow Oscar nominee and gorgeous Kenyan actress Nyong'o circulated. The media is eager to make that guy's dance card pretty full, since a source told Us Weekly that Cyrus, who split with fiance Liam Hemsworth last September, and Leto are "hooking up" and that "she stayed over at his house in L.A. in early February."

Cyrus, 21, and Leto, 42, have known each other for quite a while, but with her Bangerz Tour kicking off and his awards season run, we wonder when they'd have time to hook up.

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

If they are indeed hooking up, which is clearly unconfirmed, it's casual, not committed, since an insider said that the rocker "doesn't do girlfriends."

Alrighty then!

PopCrushers and Smilers, would J. Leto be a good BF or hook up partner for Miley Cyrus?
