So what was Miley Cyrus doing while all her musical friends were at the 2014 Grammy Awards on Sunday night? She was at home playing "Guitar Hero."

Cyrus tweeted a sad-looking pic of herself lying on a bed with a white video game guitar, just as the show was ending. "Photo from my performance this evening," she wrote to caption the pic.

Miley caught a major snub from this year's show. Her #1 album Bangerz didn't make the Grammy eligibility cut-off, but her hit singles "We Can't Stop" and "Wrecking Ball" could've (and should've) gotten noms in any of the relevant singles categories.

Cyrus wasn't the only one with other plans on Sunday. Justin Bieber, Usher and Scooter Braun were down in Panama to help sort things out with the pop singer, who was arrested in Miami earlier this week.

Photos of Justin, Usher and Braun made their way onto TMZ Sunday, while sources told the site that they all flew down for an intervention of sorts.
