The gorgeous white frock featured a sweetheart neckline, a peplum and a dramatic train – and in a true-to-Gaga twist, she topped the look off with a gold crown.
The singer was in the neighborhood for her Born This Way Ball tour and will be performing at the Manchester Arena on Tuesday, Sept 11.
What inspired the songstress’ bridal look?
No word yet on whether she was playing dress-up or preparing for something much more serious with boyfriend and Vampire Diaries heartthrob, Taylor Kinney, 31.
It wouldn’t be the first time that Gaga’s been spotted in a wedding gown.
Gaga tweeted a photo of herself and some girlfriends sporting Vera Wang bridal gowns, writing, “It’s my best friends wedding she made us try on dresses! BRIDESMAIDS VERA Baby.”
The hints didn’t stop there.
The singer also just released her fifth – and final – video for her single “You and I,” which features a wedding scene between her and Kinney. The twosome, both clad in white, kiss underneath Gaga’s veil.
The couple was seen grabbing dinner with pals to celebrate their one-year anniversary in August at Chicago’s Spiaggia restaurant.
