Solo artist Baek Seung Heon took pictures with thirteen-member hip-hop group Topp Dogg at MBC's 'Show Champion' and uploaded the pictures onto his Twitter.

Both pictures are super large group photos, but one is more normal while the other is playful.  In the playful one below, the boys are all gesturing cutely at Baek Seung Heon in the middle.
