Pop star Miley Cyrus has gone topless for one of the four alternative covers released for the deluxe edition of her new album Bangerz.

Cyrus will let her fans have the final call over which one will be chosen to be the official artwork for the deluxe edition. Fans can vote for their favourite via this link.

Cyrus hit a major milestone in her career with her latest hit Wrecking Ball debuting on number one in the Billboard Hot 100. This is also the first number one in Cyrus' career. Her singles We Can't Stop and Party in the U.S.A had previously come close at number two.

Cyrus was elated about this new accomplishment and took to Twitter to express her feelings.

"#1 on Billboard. #1 on iTunes. #1 on Spotify. #1 on Streaming. #1 on Digital songs. #1 most added to pop radio. #1 on VEVO. #WreckingBall," she tweeted.

Meanwhile, on the personal front, the 20-year-old is newly single after she announced her split from Liam Hemsworth a few days back. The couple met on the set of the 2010 romantic drama The Last Song and began dating soon after. Apparently the couple split up early this year but Cyrus was in denial over it.

"Liam has been begging Miley to announce the split all summer. He wants to go out and have fun without being branded a cheater. She's in denial. Everyone around her is worried this could have a really bad effect on her," a source stated.

"She texts him so much, especially super late at night. His friends joke about it. Liam doesn't want to be mean - but he wants to be single," the source added.

Hemsworth, meanwhile has told Cyrus that she can keep her engagement ring and reports suggest he has already moved on with Mexican actress Eiza Gonzalez. He was spotted kissing González at her apartment complex in Beverly Hills, California.
