Miley Cyrus may be moving on from Liam Hemsworth for Justin Bieber, as the singers reportedly have been flirting with one another lately. They were seen partying at the Los Angeles nightclub Beacher’s Madhouse at the Roosevelt Hotel over the weekend before leaving together around 2 a.m., sources told TMZ.

Bieber arrived at the club around 1:50 a.m. and immediately went to Cyrus’ table. They talked and flirted before heading out of the club. Earlier that day, his animal-printed Audi was also seen leaving Cyrus’ home.

Weeks ago, reports emerged that Cyrus and Hemsworth had called their relationship off after four years together.

“They are definitely over,” one source confirmed to Us Weekly. Representatives for Hemsworth and Cyrus have yet to comment on the alleged split. Hemsworth 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.”

While Cyrus has previously insisted the pair is fine, they have been spending more time apart lately and have not been photographed together in recent months.

Meanwhile, Bieber and Selena Gomez have been on-and-off for months, and were last seen together at the Billboard Awards in May, when Gomez gave him a kiss on the cheek backstage.
