Miley Cyrus engaged to Liam Hemsworth

 Who owns Miley Cyrus' heart? Liam Hemsworth officially does. A rep for the couple tells People that the pair are engaged after dating for three years.

"I'm so happy to be engaged and look forward to a life of happiness with Liam," says Cyrus, 19.

Miley met Liam, 22, on the set of "The Last Song" in 2009 and they have been together ever since. Hemsworth proposed on May 31 with a 3.5-carat Neil Lane diamond ring.

Hemsworth will soon be busy filming "Catching Fire," the second installment of the "Hunger Games" trilogy, in which he plays Gale, Katniss' close friend/love interest from District 12. Miley is currently working on a new studio album. There is no word yet on the wedding.

Congratulations to the happy couple!
