Greyson Chance Meets Lady Gaga, Tweets Photo
Lady Gaga-coverin', Justin Bieber-lookin' Greyson Chance met his idol at one of her concerts this week, tweeting: "I met @! She was so kind, gave me some great advice and put on an amazing show!!" Greyson also shared a photo of the meet-up (above).

When the 12-year-old piano prodigy from Oklahoma set YouTube ablaze in May, he quickly appeared on 'Ellen,' where Gaga made a surprise phone call, advising him to "work really hard, and stay away from girls and be focused."
