The singer, who will be performing during the award show, arrived in a custom glittery gown by Azzedine Alaia. Not only did the Tunisian-born designer create her red-carpet ensemble, he also created her three onstage looks.

"I'm so excited to perform at the #Oscars tonight. I'm honored to be wearing 3 custom Azzedine Alaïa pieces, his first ever for the Oscars," Lady Gaga wrote on Twitter. And we can't wait to see.
