Miley Cyrus Engaged: Liam Hemsworth, Actress To Wed

It's official: Miley Cyrus and Liam Hemsworth are engaged!

"I'm so happy to be engaged and look forward to a life of happiness with Liam," Cyrus told People, with the couple's reps confirming their engagement took place on May 31.

The star has yet to mention her exciting news on her Twitter account just yet, but did tweet "heaven is a place on earth" on June 1, the day after her engagement.

Cyrus, 19, has been dating the "Hunger Games" star, 22, since 2009, after they starred together in "The Last Song."

Hemsworth covered the March 2012 issue of Details magazine, and he opened up about his relationship with Cyrus.

"What happened happened, and we've been together two and a half years," he said about falling for Cyrus on the set. "She makes me really happy. When you start, you want to be professional, but when you're filming those scenes with someone and pretending to love them, you're not human if you don't feel something."

In late 2011, rumors popped up that Cyrus was engaged after she was sporting what appeared to be a diamond ring on her left ring finger . However, she denied the news at the time.

And it's clear that the former "Hannah Montana" star is all grown up. Last month, Cyrus opened up to The Sun and spoke candidly about sex.

"I think [sex] does change you as a person a little bit because you start thinking maybe that's what guys want from you," she told The Sun. "It's a big part of growing up, because it opens a whole new connection -- and heartbreak."
