This marks the duo's first time performing their Grammy-nominated hit "Just Give Me A Reason" on network television. At the big show, the COVERGIRL and the rocker are up for Song Of The Year against Bruno Mars ("Locked Out of Heaven"), Katy Perry ("Roar"), Lorde ("Royals" ) and Macklemore & Ryan Lewis ("Same Love").
Pink and Ruess are also up for Best Pop Duo/Group Performance for the track, which was used in the "Music Unleashes Us" campaign. Nominees in that category include Daft Punk featuring Pharrell ("Get Lucky"), Rihanna featuring Mikky Ekko ("Stay"), Robin Thicke featuring T.I. and Pharrell ("Blurred Lines") as well as Justin Timberlake featuring Jay Z ("Suit & Tie").
"In the past four years, both Pink and Fun. have given us some of the most memorable Grammy performances, with 'Glitter In The Air' and 'Carry On'," executive producer Ken Ehrlich said in a statement. "It was an easy and natural ask to have them perform on this year's show because their collaboration is nominated, and with these two incredibly strong voices — arguably two of the most signature voices in pop and rock — there's no doubt that viewers will be treated to a very special Grammy moment. We're working through the creative for their segment, and there are sure to be some surprises in store."
The 56th Annual Grammy Awards will go live on CBS on Sunday, January 26, 2014, 8 P.M. ET/PT.
