Miley Cyrus and Liam Hemsworth's break up might not be permanent - new information reveals the "Hunger Games" star cannot stop talking about his ex-fiancé. 

"Every time Liam speaks to Chris, he asks if he's seen the twerking queen's video or listened to her album, then babbles on how much Miley has changed," a source told ShowBizSpy.com.

"Chris finally blew his stack and ordered Liam never to mention her name again!"

But Liam Hemsworth might not be the only one in the relationship who is rumored to want to get back together.

The "Wrecking Ball" star announced her Valentine's Day tour just as she asked her fiancé to get back together.

This week Miley confirmed she would be going on a world tour with her new album Bangerz, kicking off notably on Valentine's Day, February 14 next year, EntertainmentWise.com reports.

In a recent interview Cyrus hinted that her Valentine's Day this year hadn't gone so well and that she'd actually penned a track, Drive, about wanting to be out of a failed relationship, EntertainmentWise.com also reports.  

Earlier this week, it was speculated that the "Wrecking Ball" star sent love letters to her ex-fiancé asking for him back, but a source revealed that she calls him instead.

"She's still very hung up on him but she's not writing him letters begging for him back," a source close to the Miley Cyrus told HollywoodLife.com.

"The worst she's done is call him late at night when she gets emotional. She's in a lot of pain still over this breakup so she's had a few weak moments but she always regrets it the next day."
