"I met Lady Gaga! She was so kind, gave me some great advice and put on an amazing show!!" he tweeted along with the snapshot.
Chance and some of his closest friends sat front row at the Ford Center in Oklahoma City for the pop star's "Monster Ball" concert Tuesday.
"Lady Gaga concert tomorrow..I am counting down the hours!" the estatic 12-year-old tweeted Monday.
The Justin Bieber lookalike set the internet on fire last May, posting his rendition of Gaga's "Paparazzi" after performing it at Cheyenne Middle School's 6th grade festival.
When his video went viral, Chance instantly landed an appearance on the Ellen DeGeneres Show where the Oklahoma native was surprised by a phone call from Gaga herself, advising him to "work really hard, and stay away from girls and be focused."
Just weeks after Chance's appearance on DeGeneres' show, the daytime host broke news that she'd be starting her own record label, with Chance as the first artist to sign on.
"Greyson inspired me to start a record label called eleveneleven. He is my first artist and we are making a record together," the American Idol judge said.
