Miley Cyrus will walk down the aisle with Liam Hemsworth

Famous couple got engaged, but have little time to celebrate

Miley Cyrus is all grown up now. In case you were still under the impression that Miley was the sweet, young Hannah Montana, think again: Miley's engaged! Yes, Cyrus and her longtime boyfriend Liam Hemsworth are tying the knot and there's no doubt this will be a massive celebrity wedding!

I have to confess that when Miley and Liam started dating (they met and fell in love while filming The Last Song), I never thought they'd last. I thought both of them were just too young. Apparently I was wrong, because three years after they first got together, wedding bells are about to ring. That's what I get for being so cynical.And yeah, I still think that Miley Cyrus and Liam Hemsworth are young (she's 19, he's 22) -- but hey, if they're happy, they're happy. Hemsworth proposed late last month, giving his beautiful bride-to-be a 3.5 carat engagement ring (Neil Lane, of course).

Miley Cyrus' famous father, Billy Ray Cyrus, sounded off about his daughter's engagement on Twitter, saying, "All I ever hoped for as a Daddy was to see my kids reach their dreams. To find happiness...peace of mind ...and someday know... true love." That is absolutely heartwarming, isn't it? He sounds like one proud dad!

Now that Miley and Liam are officially planning on spending the rest of their lives together, when can fans expect them to work together again? Not anytime soon, unfortunately. Both were back at work yesterday -- Miley at a photo shoot in California and Liam in New Orleans, where he's filming a movie.

So, now the big question is: When is the wedding?! The answer, for now, is unclear. A source tells People magazine that Miley Cyrus isn't into the planning stages just yet, saying, "She's playing that part by ear." Good! She's young, beautiful, talented and she has a gorgeous, equally talented fiancé. Miley should enjoy her engagement for a while, before she risks turning into bridezilla!
