After Miley Cyrus and Justin Bieber were caught partying together in L.A., the duo were quickly linked romantically.

But a rep for the actress tells EnStars, they are not dating.

TMZ first reported that Bieber and Miley were allegedly caught flirting at Hollywood hotspot Beacher's Madhouse at the Roosevelt Hotel early Sunday morning.

Sources told TMZ that Justin showed up around 1:50 AM and made a beeline straight for Miley. Onlookers claimed the two were laughing and majorly flirting.

The "Can't Be Tamed" singer called in to Hot 99.5 in D.C. this morning to address the rumors about her and Bieber being more than just friends.

Her response? "I'm ENGAGED!" she said, chuckling. "I'm engaged. That is impossible."

Her answer clears up rumors that she broke things off with Hunger Games fiance Liam Hemsworth.

During the call, Cyrus was also asked about Amanda Bynes talking smack about her, which she responded, "I won't even entertain."
