ET has reached out to the GRAMMYs and Beyonce’s rep.
The news comes one day after Queen Bey announced she and husband Jay Z are expecting twins.
"We would like to share our love and happiness. We have been blessed two times over," Beyoncé wrote on Instagram. "We are incredibly grateful that our family will be growing by two, and we thank you for your well wishes. - The Carters."
This will be Beyoncé's first performance since announcing her pregnancy. Other artists to hit the GRAMMY stage include The Weeknd, who is set to perform with Daft Punk, as well as Alicia Keys and Maren Morris, who will also collaborate on a duet. Legendary hip-hop group A Tribe Called Quest will also perform with 15-time GRAMMY winner Dave Grohl and Anderson .Paak, who is nominated for two GRAMMYs, including Best New Artist.
Adele, John Legend, Bruno Mars, Metallica, Carrie Underwood and Keith Urban are also set to sing at the GRAMMYs, while James Corden will serve as host.
The 2017 GRAMMYs will air on CBS on Sunday, Feb. 12, at 8 p.m. ET.
