The singer's headlining Thursday night at Hamburger Mary's near his hometown in Brandon, Florida. The joint's known for its burgers and drag queen shows. While the performance comes just 4 days after announcing he's also attracted to guys, TMZ was told Aaron actually booked the gig a month ago.
Aaron will perform for about an hour ... and the performance will include a compilation of his old hits and newer songs. The VIP ticket package -- which includes a meet-and-greet -- is sold out but limited tickets starting at 10 bucks are still up for grabs.
In case you're wondering ... tonight is NOT drag night.
