The 'You and I' songstress looked sensational in the crimson and baby blue number that dripped with beads and emroidery in a harlequin design and that boasted a hefty set of 80s inspired shoulder pads.
But it was the travelling split that really grabbed our attention!
Lady Gaga showed off her black and white inkings as her dress rode up while she sauntered her way into the red carpet venue alongside fiancé beau Taylor Kinney but she still looked every inch the Hollywood siren thanks to her cascading bleached waves and a scarlet lip to boot.
Never one to follow the fashion rulebook, Gaga teamed her red dress with a pair of hot pink satin court heels but totally owned the mismatched look as she rubbed shoulders with the likes of legendary musicians Paul Simon and Tony Bennett.
During the evening, Lady Gaga took to Instagram to personally thank fashion maestro Marc Jacobs for lending her the dazzling outfit. She captioned a snap of herself: "Thank you Marc Jacobs I felt so beautiful and also like me all night. What an incredible piece, fit me like a (good) glove!"
Simple just wouldn't cut it for the blonde haired beauty whose eye make-up was nothing short of lash-tastic, and she topped off the look with two silver ear cuffs that featured punky rings and countless gleaming rhinestones.
She definitely pulled it off. And there wasn't a nip slip in sight - hurrah!
