Adele will make her long-awaited return to the stage on Feb. 21 at the Brit Awards, organizers for the event confirmed. This will be her first appearance since she underwent vocal-cord surgery in November.

"F---ing happy, thank you for the nods xx," Adele tweeted on Thursday, responding to her three nominations at the Brits.

Now, the big question is whether or not she'll be able to perform at the Grammys, where she's up for six nominations, including Song and Record of the Year for 'Rolling in the Deep' and Album of the Year for '21.' The ceremony will take place on Feb. 12.
