Los Angeles: Singer Miley Cyrus has shared on Instagram a video of her and boyfriend Liam Hemsworth singing along to a Justin Bieber song. In the video, viewers get to see the pair's pet dog Barbie, a little bit of Cyrus' face as the "Wrecking ball" hitmaker, and her actor beau for a duet of Bieber's track "Love yourself", reports aceshowbiz.com. At one point in the video, Hemsworth screams in an attempt to scare Cyrus, prompting her to yell, "Babe, stop! Seriously!" Hemsworth and Cyrus, who began dating after meeting on the set of their 2010 film "The Last Song", got engaged in 2012 before breaking up in 2013. They rekindled their romance late last year, and she has since been spotted wearing her engagement ring again. The pair is said to be getting married in Australia later this summer.
