Rebound romance? Two can play at that game! Just days after Liam Hemsworth was spotted making out with Mexican actress Eiza Gonzalez, his ex-fiancée Miley Cyrus has gone public with her own new relationship, with rapper and producer Mike WiLL Made It. The two were spotted getting touchy-feely backstage at the iHeartRadio Festival in Las Vegas and even hanging out with her family!

Cyrus and the producer, born Michael Williams, first met when he produced her hit single "We Can't Stop." She subsequently appeared on his song, "23."

According to Star magazine, they started hooking up even before her split from Hemsworth was announced. An insider told the mag, "Everyone knows they're hooking up."

And if they didn't then, they do now.

On Saturday, Cyrus was spotted leaning in for a hug with the rapper while she was wearing pasties and a thong under a mesh dress with fur sleeves for her iHeartRadio performance.

That same day, her sister Brandi spilled the beans when she posted a pic of the "Wrecking Ball" singer and her new man hanging out on a party bus with her mom, Tish and friends.
