Miley Cyrus and Liam Hemsworth Announce Engagement

Miley Cyrus and Liam Hemsworth Announce Engagement

Miley Cyrus is getting married!  And her fiancé is seriously hunky.

He's Hunger Games actor Liam Hemsworth.

The engagement is bound to raise eyebrows because Cyrus is just 19 years old. Hemsworth is 22.

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

"Even though Miley is 19, a source tells People that her parents are thrilled by the news, and so are Liam's parents, and that the Cyrus' consider Liam part of the family," said People magazine's Joey Bartolomeo.

Cyrus has been dating the handsome Australian-born actor for 3 years. They met when they shot the movie The Last Song.

He proposed just last week with a 3.5 carat diamond ring.

Good looks run in Hemsworth's family—his brother is heartthrob actor Chris Hemsworth, who plays Thor, and is currently starring in Snow White and the Huntsman.

Cyrus has been growing up before our eyes since becoming a teen idol in Hannah Montana. During a recent appearance at the Billboard Music Awards, she wore just a white tuxedo jacket—and not much else.
