Miley Cyrus Engaged to Actor Liam Hemsworth

Singer, songwriter, and actress Miley Cyrus is engaged to her on-again, off-again boyfriend of three years actor Liam Hemsworth.

The 19-year-old celebrity, who is the daughter of country music star Billy Ray Cyrus, became engaged to the 22-year-old actor on May 31 but news of the engagement was reported Wednesday morning by People magazine.

Hemsworth proposed to the star with a 3.5-carat diamond ring from jeweler Neil Lane, the magazine reported.

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

Hemsworth is a native of Melbourne, Australia and his acting credentials include the recent blockbuster "The Hunger Games." He co-starred with Cyrus in the 2009 film "The Last Song."

In an interview earlier this year, Hemsworth told Details magazine that he fell in love with his future wife on the set of "The Last Song."

"What happened happened, and we've been together ever since," he said. "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," the Australian actor shared.

On Wednesday morning, Cyrus took to the social networking site Twitter to tweet to her followers "life is beautiful."

Celebrities and fans of the two stars have also taken to the social media website to comment on the engagement news.
