On the heels of the recent announcement of Miley Cyrus' and Liam Hemsworth's engagement yesterday, one can't help but worry for the couple being in a rush to marry despite their three-year relationship.

So, is this another publicity tactic from the Team Miley boot camp?

It's no surprise that the former teen superstar's career slowed down after her landmark Disney Channel series, Hannah Montana, ended in early 2011. However, even before that, her Can't Be Tamed album wasn't received well by the public, as the "mature" image Cyrus conveyed here only fuelled the fire caused by previous controversies. Examples are her 2009 Kids' Choice Awards performance, the viral lap dance video with director Adam Shankman and the "Salvia" incident.

On the other hand, Hemsworth's star has been on a steady rise, as proven by his involvement in the successful The Hunger Games film as Katniss' other love interest, Gale Hawthorne. This plum role has given him the long-due momentum that would land him other movie projects such as the highly-anticipated The Expendables 2 and the war drama Love and Honor later this year.

The possibility only grew more when Miley changed management recently. Although it's publicly said that the revolution was to give her career a boost, especially her music, who knows what other aspects of the actress' life they would dive into to regain the glory she once had.

Even Cyrus' father Billy Ray wasn't much ecstatic about the announcement. Sure, Billy sees the Australian actor "like his own son" and a good influence to his daughter, but a source close to him dishes to CelebrityFix how concerned daddy Cyrus is regarding how young the couple is.

"He hopes that they aren't in a rush to get married. Billy Ray hopes the engagement will be very long, but he isn't opposed to the marriage at all," the source said. "Billy Ray got divorced from his first wife Cindy though and he just doesn't want Miley to go through a similar heartbreak."

As far as Hollywood couples go, survival rate for any marriage is dismal, but only time could tell if we would hear "the last song" about the two as well.
