On Wednesday it was announced that four-time Grammy winner Bruno Mars will perform onstage for the first time since his memorable performance at the award show in 2013. Even though Mars' latest album, 24K Magic, was an absolute smashing success, its release date actually missed the deadline for eligibility for the 2017 show. Despite that, Mars is still up for a nomination this year for his work on Adele's hit album 25. The 59th Annual Grammy Awards, which will be hosted by James Corden, are scheduled to air on February 12 on CBS at 8 PM.
