Miley Cyrus has ended her short-lived relationship with Kellan Lutz after being rumored to be with him for the sex life, leaving many fans if the "Wrecking Ball" star may have split with Liam Hemsworth for similar reasons.

"[They] are not really hanging out anymore [because of] their hectic schedules at the moment ... just kind of burned out," a source told PerezHilton.com.

Miley Cyrus was spotted sporting a new bowl-cut hairstyle earlier this week and has received criticism from several sites about the choice, leaving many fans wondering if her split with Liam Hemsworth may have involved her choice of hairstyle.

The "Wrecking Ball" singer changed her haircut numerous times throughout 2013, with both short and long styles.

Miley Cyrus and Liam Hemsworth may have split for good - the "Wrecking Ball" singer is allegedly "no longer speaking" to her ex-fiancé.

"She doesn't speak with Liam," a source told HollywoodLife.com.

"She has another life now that doesn't involve him. When she was with him, she only thought marriage, now she can only think of life without him and to her, it's so far so good."

Miley Cyrus mentioned on Twitter that she does not mind being called a Lesbian, leaving many fans wondering if she's made an official public announcement about her sexuality.

"I get called an ugly lesbian a lot more than one would think. Or maybe not," she wrote in a Twitter post.

"Can u atleast call me an interesting lesbian. I hate the U word."

Last week, it was reported that she was rumored to be using Kellan Lutz to satisfy her sexual life, PerezHIlton.com reports, leaving many fans wondering if her split with Liam Hemsworth left her hungry for hookups.

"She says she's using him for sex," a source told the website.

"But she's starting to care about him."
