Miley Cyrus didn't attend the 2014 Grammy Awards on Sunday night, but that doesn't mean she didn't put on a show. The singer got in on the fun on Saturday when she performed at Clive Davis's annual Grammys preparty, but she had proclaimed on Twitter that Sunday would be her "day off," meaning that she would definitely not be attending the award show. (Miley wasn't nominated for any awards or slated to appear, so it wasn't really a surprise.) However, she did reveal that she had a "performance" of sorts, thanks to Guitar Hero. She tweeted out last night, "Photo from my performance this evening," with a shot of herself lying on a couch with a Guitar Hero controller. She also posted a video of her "performance" on Instagram, showing her rocking out in pajamas to Kiss's "Rock and Roll All Night."
