But now that its Oscar season, gossip-mongers have moved onto the likes of Jared Leto, whose Dallas Buyers Club role earned him rave reviews and a Best Supporting Actor Award.
Us Weekly reported Wednesday that the 21-year-old "Wrecking Ball" singer and 30 Seconds to Mars frontman have bonded over "art and music."
They are also "hooking up."
"They like to have a good time, they love to talk about art and music -- and they're both comfortable with nudity!" a source told the mag.
Both stars attended Clive Davis' pre-Grammys party last month, where Cyrus performed.
