You may not love her music, but you have to respect the lengths to which Lady Gaga will go for her fans. Saturday night, she was the talk of ... Louisville.

After a show at the KFC Yum! Center (yes, that is a real venue), she hit a gay bar called Connections, where a Gaga impersonator show was in progress.

Gaga popped up on stage around 1:15 a.m., right in the middle of her hit song, "Born This Way." She proceeded to join this faux Lady in a duet! Watch:

The Two Lady Gagas

She'd already performed her smash hit song in concert, but this rendition at the club, where she showed up unannounced, was likely more memorable.

Following the duet with her 6-foot doppelganger, Gaga did a stage dive into the crowd before strutting off stage to the delight of stunned club-goers.

Don't be a drag ... just join a queen on stage. She rules.
