Garth Brooks has quite the fanbase -- celebrities will no doubt be flocking to his comeback tour shows, and worldwide superstar Lady Gaga is no exception.
Luke Bryan did a recent show, and tweaked his live playlist to include some Lady Gaga, and the Hairband Poison. He performed Gaga's "Bad Romance", and really put some Umph into it. Then the band went into Poision's "Nothin' But a Good Time".
The 2011 Grammys may have been Gaga's show, but people actually won some awards, too. Biggest shocker (maybe?) was unknown songstress Esperanza Spalding making enemies with a nation of Justin Bieber fans by taking Best New Artist. And Lady Antebellum winning pretty much everything else. Here's a good chunk of the winners, and photos from many of the performances.
