Miley Cyrus and Liam Hemsworth on the red carpet Tumblr

Miley Cyrus and Liam Hemsworth reunited for the premiere of his latest movie, "Paranoia," on Thursday in Los Angeles, amid allegations that the engaged couple is on the rocks. The 20-year-old wore a Proenza Schouler Spring 2013 red, black, and snakeskin perforated leather dress, along with a pair Céline white pumps and a Chanel bag.

She looked quite happy as she posed with Hemsworth on the red carpet, who kept his look simple with a gray-and-black suit.

The Australian actor proposed to Cyrus in May 2012 with a 3.5-carat diamond ring. They began dating in 2009 after co-starring in the film “The Last Song.” But it had been speculated for the past few months that Cyrus and Hemsworth had called their relationship off after four years together.

Just back in March, sources told New York Post’s Page Six, “Miley and Liam are done; it’s over. She likes to party really hard and can be pretty wild. It became a problem for him.”

“They have broken up before and are broken up again now. There was drama, because she suspected he had a wandering eye. And she recently tweeted a denial that he cheated. While Miley has insisted they are still together, right now they are very, very much apart,” another insider added.

However, while they have rarely made public appearances over the past six months or so, it seems the pair is still together, and engaged, as Cyrus made sure to wear her engagement ring at the movie premiere. Even still, a source told Us Weekly that "Miley and Liam acted like they didn't even know each other the entire night. She was wearing her ring but they acted as if they were strangers."
