The 26-year-old superstar is currently performing her Born This Way Ball shows in Australia, but took time out to host a lavish Fourth of July bash for her staff in Melbourne, reported Contactmusic.
Gaga reportedly partied with around 150 pals at the city's Northcote Social Club and pictures from the event were posted on Twitter and on the venue's Facebook page.
"Everyone had a good time and everyone was lovely to deal with. It was a great night," said a spokeswoman for the club.
Guests were treated to barbecue and were entertained by Australian drag queen DJ Kitty Glitter and Gaga's band.
