UPDATE: Miley Cyrus has taken to Twitter today to deny that she is engaged to Hunger Games actor Liam Hemsworth, thanks to a large, sparkly rock on her left ring finger spotted at multiple events over the last week. “I’m not engaged,” Cyrus tweeted. “I’ve worn this same ring on this finger since November! People just wanna find something to tal about! It’s a topaz people!” The pair has been dating since costarring in 2009’s The Last Song.
