The pants-free star recently checked into a well-known gay western bar in Texas that gave her a gig when she was just starting out as an artist.
Rocking up to The Round-Up Saloon in a limo after a show in Dallas, Gaga was trailed by two police escorts and an entourage of 15 - including her mum.
Declaring to the bar's owner that she was "here to party", she ordered drinks in an upstairs loft while people tried to pack into the 850-capacity bar after hearing she was inside.
After 45 minutes of 'partying' and exactly two glasses of Jameson and water, Gaga had to leave, taking some cute snaps with staff before making her fabulous way out into the night.
Owner Alan Pierce told TheCount.com that his famous patron was "nice and wonderful now, as she was before she became a big star."
