The Best Looks From The 2015 Emmys After-Party (PHOTOS)

Spoiler alert: Lady Gaga slays again.

In the famous words of R. Kelly, "After the show it's the after-party."

Once host Andy Samberg signed off on the 2015 Primetime Emmys, which aired on Sunday evening, the big winners of the evening and fellow nominees stormed a few of the after-parties kicking off around Los Angeles. HBO and FOX both hosted star-studded parties that saw some of the nominees perform a little costume change.

Lady Gaga changed out of her gorgeous black Brandon Maxwell gown for another creation by the designer, this time in white, while Laverne Cox transformed out of her teal Calvin Klein gown and slipped into a stunning white cutout dress with thigh-high slits. And finally, the ladies of "Modern Family" swapped out their red carpet gowns for sexy, black frocks.

Check out the show-stopping Emmys after-party looks below:
