Miley Cyrus' ex-fiancé Liam Hemsworth is worried about her personal life and even contacted the "Adore You" singer while she spent the weekend in the hospital, the Hollywood Gossip reports.

"He was extremely worried when he heard she was in the hospital," a source close to Liam Hemsworth told the site.

"They didn't work out as a couple, but he still wants to know she's okay."

Miley Cyrus' Bangerz Tour St. Louis concert cancellation has sparked conversation among disappointed "Adore You" and "Wrecking Ball" fans on Twitter and Instagram.

Liam Hemsworth 's ex-girlfriend made the announcement that she is cancelling her Bangerz Tour concert in St. Louis via Twitter and Instagram while being treated for a severe allergic reaction.

"I can't get a hold of my team because it is so early so I want to be the one to tell my fans especially the ones trekking to get there," the "Adore You" singer writes.

"The hospital is saying i wont b released today therefore im not going 2 make it 2 St. Louis. Im so sorry but somethings are outta my control."

Miley Cyrus posted a topless photo of herself on Twitter and Instagram with a towel wrapped around her naked body with an unknown man getting off of the bed behind her.

Did the "Adore You" singer post a picture of the new person she may be dating and is it possible they may have been publicizing their sexual relationship?

Liam Hemsworth's ex-fiancé cancelled her Bangerz Tour concert in Charlotte, N.C. on Monday because of the flu, the New York Daily News reports, but many on Twitter and Instagram are saying it may be related to her rumored depression.

The Bangerz tour singer revealed during a recent interview with Elle magazine that there was a time when she thought she would die without Liam Hemsworth following her break up, the New York Daily News reports.

"When I was with (Liam) or when I was on Disney, the thing that gave me the most anxiety was not knowing what to do with myself when Disney wasn't there to carry me anymore or if I didn't have him," the "Wrecking Ball" singer said, according to the site.
