Lady Gaga steals the show at the National Board of Review Awards 2019: See what all the stars wore!

All about Gaga.

The 2019 National Board of Review Awards brought together some of awards season's key players at Cipriani 42nd Street in New York City on Tuesday, two days after the Golden Globes, and Lady Gaga completely stole the show.

The star, who won the Best Actress award for her leading role in "A Star Is Born" at the show, was a total vision in a custom Ralph Lauren tuxedo-inspired halter gown, which was covered in over 23,000 crystals. She paired it with a hand-painted gold-and-black feather cape that gave the glamorous look a true Gaga flourish.

Also in attendance on Tuesday night was Golden Globe winner Regina King, as well as Constance Wu, Bradley Cooper, Maggie Gyllenhaal, Olivia Wilde, Gemma Chan and Sophia Bush.
