The pair stepped out together to support Liam's older brother, Chris Hemsworth, at the Los Angeles premiere of The Huntsman: Winter's War on Monday night to the delight of fans everywhere, and now we've got the exclusive pics.
The couple was careful not to show too much PDA, although Miley hung on to Liam's arm as they exited their car.
Miley later had her arms around a female friend as Liam, 26, walked ahead.
After the premiere, Miley and Liam headed to Baltaire restaurant at around 11 p.m. with a couple of friends, including Liam's brother Luke. The group "was very rowdy and having a good time," an eyewitness tells ET. Miley and Liam left the restaurant at around 12:15 a.m. and went home together.
Miley and Liam's last public red carpet appearance together was back in August 2013 for Liam's film, Paranoia, but the two split one month later. Rumors that Miley had rekindled her romance with her The Last Song co-star started in January, when they were spotted together in Liam's home country of Australia.
Since then, things have been moving pretty quickly between the two. In January, the 23-year-old singer was snapped bringing a U-Haul truck to Liam's home in Malibu, California, creating speculation that the two are living together. She's also been re-wearing the dazzling Neil Lane engagement ring Liam gave her when he first proposed to her back in summer 2012.
Miley was spotted having lunch with Liam and his two brothers -- Chris and Luke, as well as Luke's wife, Samantha -- last Friday at Gracias Madre, an all-vegan, organic Mexican restaurant in West Hollywood, California. An eyewitness told ET that the "Wrecking Ball" singer appeared "happy and relaxed" as they were photographed leaving the popular eatery.
