Miley Cyrus and Liam Hemsworth officially called off their engagement on September 16, but the last thing this pop diva is doing is sitting around eating ice cream and watching The Last Song.

Instead, the controversial starlet might be sparking up a new romance — and she's keeping it close to home. Miley and her Atlanta-based music producer, Mike WiLL Made It, are rumored to be hooking up and based on photos of them getting super close in Las Vegas on September 22, we're starting to be more convinced.

Miley and Mike were seen canoodling at the iHeartRadio music festival after Miley's tearful "Wrecking Ball" performance. While she definitely looked emotional on stage, her mood seemed to change during her embrace with her producer. Splash News reports that Mike was even chatting with Miley's mom Tish while she posed with fans.

Between these two getting touchy-feely, Miley being on the rebound, and Mike getting close with mama, we're definitely more suspicious of a romance. After all, Liam has been seen kissing his new girl Eiza Gonzalez, so Miley may not be holding back.

What do you think is going on between Miley and Mike? Could they just be work buds or does it seem like something more? Sound off below!
