Here comes the Gaga!

Adding to her list of over-the-top ensembles, Lady Gaga stepped out in London, England on Sunday dressed up as a bride.

The 26-year-old "Marry the Night" singer wore long white wedding gown that featured a peplum and long train to the 2012 Paralympic Games After-Party at the Arts Club. The singer risked a nip slip in the plunging neckline and reveled major sideboob to photographers. To accessorize her bridal look, Gaga wore white gloves and a gold crown over a veil-inspired headpiece.

The only thing missing? A groom! Gaga attending the party with her pals Rihanna and Jay-Z, but boyfriend Taylor Kinney wasn't on her arm.

Gaga and the 31-year-old Vampire Diaries star met while filming her music video for "You and I" in July 2011. Us Weekly broke the news of their relationship in November. They briefly split in May 2012, but have since rekindled the flame.

"They are going to try and make it work even with her crazy schedule," a source told Us. "Gaga realized she missed him."
