Beyoncé was red hot on a night out with Jay-Z on Saturday.
The two celebrated with family members at their niece Teanna's 21st birthday party, which had a Great Gatsby theme and took place in New York City.
Beyoncé sported a sexy custom one-shoulder beaded merlot Walter Collection gown with a high slit and sweetheart neckline, paired with Jimmy Choo Viola sandals and a white jade cuff with Colombian emeralds by Lorraine Schwartz —the same piece of jewelry she wore while revealing her pregnancy with the couple's first child, daughter Blue Ivy Carter, at the 2011 MTV VMAs.
Jay-Z wore a white and black tux and carried a white cane to the birthday bash.
Beyoncé posted several photos of her and her husband posing in their outfits on her Instagram page. At the party, guests also donned "roaring '20s" fashion styles.
"Beyonce and Jay-Z had a great night out at his niece Teanna's 21st birthday party in New York on Saturday night," an eyewitness told E! News. "They arrived on a party bus with lots of Jay-Z's family. All of his nieces and nephews and cousins were there ready to party and celebrate. Beyonce looked very comfortable and close with Jay's family. She knew everyone and they were all hugging and talking. Jay had a cane to go with his costume, but he was still helping Beyonce get out and get inside."
