R&B superstars Alicia Keys and Frank Ocean have been tapped to perform at the 2013 Grammy Awards, officials announced today (Jan. 31).

The 'Girl on Fire' songbird will join Maroon 5 for a special performance at the big music event.

It's been widely known that Ocean was slated to perform at the ceremony after he let it slip earlier this week in a tweet after his much-publicized fight with Chris Brown. The Odd Future crooner said that he cut his finger and "[couldn't] play with two hands at the Grammys." But it appears that he's ready to hit the stage next month.

Keys and Ocean join a star-studded list of performers including Justin Timberlake, the Black Keys, Rihanna, Mumford & Sons and Taylor Swift. Rapper-actor LL Cool J returns to host the event for the second year in a row.

Ocean is up for six Grammy awards, including Album of the Year ('Channel Orange') and Record of the Year ('Thinkin Bout You'). Although Keys didn't receive any nods this year, her 'Girl on Fire' producer, Salaam Remi nabbed a Producer of the Year nomination.

CBS will broadcast the 55th annual Grammy Awards on Feb. 10 at 8 p.m. ET.
