Miley Cyrus continued her relationship with Liam Hemsworth for months because she thought she was pregnant, PerezHilton.com reports, leaving many wondering if her "Wrecking Ball" single was about her drama with her ex-fiancé.

"Miley thought she was expecting and wanted to announce it to the world, even before she went to the doctor to verify the results. Liam begged her not to go public yet. He was emotionally out of the romance for months by that point, though he was still sleeping with her. She agreed to stay quiet for Liam's sake," a source told PerezHilton.com.

"[Miley] essentially trapped Liam in the relationship, telling him that if he left her alone, she'd tell the world that he had abandoned her at such a delicate time. She begged him to stay and said that he could have his space, as long as he didn't break up with her. So Liam obliged. He got his freedom and she got the right to say they were still engaged."

Miley Cyrus reportedly cried during a "Wrecking Ball" performance at the iHeartRadio Music Festival in Las Vegas on Sunday while Liam Hemsworth was spotted kissing his new lover Eiza Gonzalez.

Throughout their time together, Miley Cyrus was at the forefront of denying rumors about a possible break-up and holding the couple together by visiting Liam Hemsworth at his movie sets, but the same can't be said for the "Hunger Games" star.

Liam Hemsworth dumped Miley Cyrus just weeks after her raunchy VMA performance and the "Hunger Games" star wants his former fiancé to keep the $250,000 engagement ring he gave her last May, the New York Daily News reports, leaving many wondering if it was a pity gift.
