Miley's thrilled... a dream man and a diamond ring!

MILEY Cyrus declared today that "all my dreams are coming true" after announcing her engagement.

The 19-year-old former Disney Channel child star added that she can't wait for her life with 'Hunger Games' actor Liam Hemsworth.

Cyrus, whose Hannah Montana TV series made her a teen idol, said she was engaged to marry her Australian boyfriend Hemsworth (22) after a three-year romance.

The news quickly became one of the world's top trends on Twitter, bringing thousands of congratulations from fans, as well as questions over the wisdom of settling down so young. Cyrus and Hemsworth have been dating on and off since meeting in 2009 on the set of film romance The Last Song.

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

"Thank you for all the love today. I'm happy to share this news with you all. I feel like all my dreams are coming true," she posted on Twitter. Cyrus's father, country singer Billy Ray Cyrus, who starred with her on Hannah Montana, said he was delighted.

"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," he told website HollywoodLife.com.


Hemsworth proposed on May 31 with a 3.5-carat diamond ring. No wedding date was announced, but talk quickly turned to whether they were too young for such a commitment.

Cyrus was 12-years-old when she landed the part of a pop star by night and regular schoolgirl by day in Disney Channel's Hannah Montana.

But when Cyrus quit the show at age 16, she also moved fast to shed her squeaky-clean image, performing in sexy outfits and making raunchy music videos.

Cyrus put her music career on hold two years ago to focus on acting, but her latest film, LOL was a box office flop that was quickly released on DVD.

And not everyone was feeling the love for the young couple. "Miley Cyrus and Liam Hemsworth are engaged. Please excuse me while I stick my head in an oven" tweeted Girl's Got Issues.
