After dilly-dallying it for long, teen pop sensation Miley Cyrus has finally got engaged to her long-time actor boyfriend Liam Hemsworth. Though earlier it was reported that Liam is not ready for marriage and commitment yet, the latest buzz is that the Hunger Games star has proposed to the former Hannah Montana singer-actress with a 3.5-carat diamond ring last Thursday, People magazine reported. "I'm so happy to be engaged and look forward to a life of happiness with Liam," Cyrus said. The 19-year-old has been dating the Aussie star for the past three years, since they met in 2009 on the set of their film The Last Song. Except a brief split in 2010, they are together since then. While Cyrus is presently busy with a new album, Hemsworth is all packed up with films like Empire State, Paranoia with Harrison Ford and Gary Oldman and Hunger Games-2.
