On Friday and Saturday nights, Miley Cyrus and six girlfriends stepped out at Miami hip hop club, Cameo, where the group – who was seated at a VIP table – danced from midnight to 4 a.m.
"Miley was the life of the party both nights," an onlooker tells PEOPLE. "She danced to songs by 2 Chainz, Kanye West and Jay-Z while showing off her hot physique."
Also out for a night of clubbing was Ke$ha, who was spotted "laughing and bumping and grinding," with the "We Can't Stop" singer, adds the source, after they both performed at the Fontainebleu's iHeartRadio Ultimate Pool Party on Saturday.
When Cyrus wasn't dancing or waving at fans, she appeared to be "having a great time requesting songs with the deejay," the source says.
