TMZ recently obtained photos of pop songstress Miley Cyrus partying at an LA hotspot late Saturday evening (June 8)... alongside 19-year-old "Believe" crooner Justin Bieber. Apparently the Biebs showed up to the Beacher's Madhouse at the Roosevelt Hotel a little before 2 a.m. - both teen heartthrobs were spotted leaving the club (together) just moments later. Is Selena Gomez's ex hooking up with the former Disney starlet, or are the two young celebs just really good friends. Perhaps they're working on a secret music collaboration together...

According to TMZ, Bieber and Cyrus were definitely "hardcore flirting" at the popular Hollywood hangout. Check out the photos here.

The Beacher's Madhouse is Cyrus' stomping grounds... she arrived earlier in the evening. Bieber didn't show his face until about 1:50 a.m. and he allegedly headed straight towards Cyrus' private table once we entered the club. Fellow partiers witnessed the two "laughing and flirting" before leaving the venue at around 2 a.m. It remains unknown where the ended up afterwards.

As Mstars previously reported, Bieber's leopard print Audi R8 was spotted pulling away from Cyrus' Toluca Lake home earlier Saturday afternoon...

So what's the deal? Are Bieber and Cyrus currently working on a music project together, or is there something moe going on between the two young pop stars?

UPDATE:

During a recent interview with Hot 99.5 in Washington, D.C., the "We Can't Stop" singer was asked about a potential Justin Bieber romance:

"I'm engaged. I'm engaged. [It's] impossible," Cyrus said.
