The Wanted are known for breaking out into fits of laughter mid-performance and during interviews. They also can spontaneously break into song, like they did in these two videos.

At the Wango Tango a few weeks ago, they were asked what their favorite summertime song of the moment (read: current) and Tom Parker and Max George chose Carly Rae Jepsen‘s ‘Call Me Maybe.’ It turned into a red carpet sing off, with Parker jumping and singing the chorus. Earlier, Nathan Sykes said that ‘Glad You Came’ is his fave. We’ll allow him the shameless self-promotion.

During a web chat, Parker sings a bit of Justin Bieber‘s ‘Boyfriend’ before he and his bandmates break into a roaring fit of laughter.

Always giggling, those guys! Boys will be boys.
