No, Jimmy, you're not dreaming.
On Wednesday night's "Jimmy Kimmel Live!", Britney Spears took a page from Rihanna's playbook and snuck into the host's bedroom for a surprise performance ... at 1:43 AM.
In case you forgot, RiRi pulled the same stunt for an April Fool's prank last year, when Kimmel's wife let her into their home for an early morning performance of "Bitch Better Have My Money."
For Brit Brit, she decided to give him an impromptu rendition of her new single, "Make Me," and was accompanied by a horde of backup dancers, strobe lights and more for the boudoir routine. Jimmy's face when two of her male dancers gyrate in his face: priceless.
Spears' performance comes after she announced her new album, "Glory," will drop August 26. Pre-orders started last night on iTunes, with her single "Private Show" available immediately.
