Beyoncé posted the first photos of her twins to Instagram late Thursday and officially announced their names: Sir Carter and Rumi.
The twins, 1 month old on Thursday, were the latest addition to Beyoncé and Jay-Z's family, alongside 5-year-old daughter Blue Ivy. Within 30 minutes of debuting on Instagram, the picture had received more than 1 million likes.
The musical superstars filed trademark applications in the U.S. for the twins' names late last month, TMZ reported. The pair did the same for Blue Ivy when she was born.
