It looks like Miley Cyrus and Liam Hemsworth are officially back together! The two were spotted secretly slipping into the Los Angeles premiere of "The Huntsman: Winter's War" Monday night to support his older brother Chris Hemsworth, who is the star of the film.

The singer and the actor did not walk the red carpet together at the Regency Village Theatre in Westwood Village, Calif., but did stay for the entire film before exiting right before the lights came on. The two left "hand in hand," according to a source at the theater.

"They were smiling and looked happy to be together," the source said. "Miley [was] looking adoringly up at Liam as he led her out of the theater."

The couple was also spotted by a fan who took individual pictures with Cyrus and Hemsworth and excitedly shared the news with all of her Twitter followers. "For all you assuming I tell lies...#MileyCyrus #TheHuntsman #liamhemsworth," she captioned her tweet along with the photos of the two.

"Miley and Liam are at this premiere together and I met them both I'm literalllyyyyyyyyyy dying. #TheHuntsman," Kayla Hockman also wrote.

"Miley and Liam are totes back together, FYI," she continued.

The rumors that Hemsworth and Cyrus were back together first came back in January when the "Wrecking Ball" singer was spotted spending time with the Hemsworth family in their native Australia. Multiple sources then confirmed the two were not only back together, but also engaged again. The rekindling of the couple's romance was apparently a long time coming, with Cyrus never truly getting over her ex.

"She feels like they could pick up right where they left off. Miley has never gotten over Liam and always hoped they would get back together," a source close to Cyrus said. "She doesn't know where it will go, but she definitely still loves him."

Last week, Cyrus and Hemsworth were seen out together for lunch along with Hemsworth's brothers Chris and Luke and their respective wives.

Cyrus, 23 and Hemsworth, 25, first met on the set of the Nicholas Sparks film "The Last Song" in 2009 and got engaged in May 2012, but ended the relationship in September 2013. Since the two broke up, Cyrus was linked to Patrick Schwarzenegger and Victoria's Secret model Stella Maxwell.
