The "Party in the U.S.A." singer was doing just that this weekend!
While Hemsworth was in New Orleans filming his new movie, Cyrus and her entourage of girlfriends made a beeline for her usual table in the front row of the club.
"Miley spent most of the night dancing," an onlooker told PEOPLE.
And the newly svelte star yet again showed her love for fellow singer Rihanna:
"She threw her hands in the air when the deejay started playing, 'We Found Love,'" the source says. "She was very chatty and was in a great mood. At around 12:15 a.m., she pulled her girlfriend into the photo booth to take pictures together."
Even though Miley is engaged, she's still only 19, and what 19-year-old doesn't love to rage to RiRi at the club?!
