Bruno Mars sang his latest single 'The Lazy Song' during his first appearance on the show 'American Idol'. Show host Ryan Seacrest was very excited about Bruno's first 'Idol' performance. One his Twitter page, he tweeted, "I think that may have been the first time we've had a dog on stage at #americanidol. Great job @brunomars."
However, Crystal Bowersox was also a musical guest the night. The 2010 Idol runner up performed the song 'Ridin' on the Radio'. Meanwhile, Casey Abrams, who was on the bottom three, was finally eliminated from the contest.
