After a tough engagement break up with Liam Hemsworth last year, Miley Cyrus is allegedly still bearing the heartbreak.

The singer, together with her friends, did some wild antics in Greenwich Hotel in New York City. Life & Style reported that the group's actions resulted to the filing of numerous complaints from hotel guests.

An insider told the magazine, "It was like a tornado hit the lobby. Miley and her posse took over, screaming and carrying on so much that management received a number of complaints."

"It was the kind of bad behavior you'd expect from a bunch of juvenile delinquents," the source added, revealing that someone from the group was also smoking pot.

Accordingly, the management tried to ask Miley and her friends to tone down their behavior. However, the actress responded with a "public meltdown."

"She started screaming at them and saying that she's spent so much money there that they should be glad to have her. She basically threw a tantrum and acted like a spoiled brat," the insider revealed.

According to Fashion & Style, her recent antics could be a sign that the singer has not yet moved on from her break up with ex-fiance Liam.

Before this, Miley has been caught up in a series of controversies for her provocative stunts following the separation.

Meanwhile, Liam has allegedly opened up about the controversial split with the former Disney child star.

According to Mail Online, a source leaked to New York Post that the actor told his companions that he and Miley had a "powerful connection."

An insider told the publication, "Liam kept raving about how amazing she was, how much they clicked and understood everything about each other."

This is the first time that the "Hunger Games" star has spoken up about the matter after keeping mum on the issue for almost a year. The two had broken up their engagement last August 2013.
