Missing the 2012 Teen Choice Awards to spend time with her fiancé, Liam Hemsworth, in Philadelphia, Miley Cyrus is staying close to her man and now she wants Emma Roberts to back away. A Cyrus- Roberts feud is brewing over Cyrus's concern that her fiancée is spending a little bit too much time getting cozy with Roberts.

Reportedly, Cyrus is fuming over the fact that Hemsworth is spending plenty of time with Roberts, his "Empire State" co-star. Cyrus is "terrified" that Roberts is "trying to steal her sweetheart," the National Enquirer reported.

"Not only did she tell Liam it had to stop, she even confronted Emma," a source said. "Miley more or less said, 'Hands off my man!'"

Cyrus is also sporting a new blonde hairdo that might have something to do with Emma Roberts, a blonde herself, being too close for comfort to her man, according to Perezhilton.com

"Miley's being super-protective since she and Liam got engaged. She's worried that while he's off making movies with hot women, he'll be tempted to cheat," a source told Celeb Gather.

Cyrus,19, and Hemsworth,22, announced their engagement in early June. Both have already mentioned that they want to start a family, and soon too.

An insider close to the couple said they both want to have a baby quickly and are ready and mature for the responsibilities of having a family.

Reports have also been indicating recently that Cyrus is perhaps choosing love over her career - skipping out on opportunities and missing events so she can constantly be with Hemsworth. She missed accepting her Choice Female Hottie at the Teen Choice Awards on July 22. However, she did remember her fans and later wrote on Twitter, "So sad I [wasn't] able to be at TCA tonight! My fans are amazing! Thank you beyond! TCA is my favorite cause it comes from y'all I love u."
