The Jonas Brothers kicked off their tour at Yankee Stadium in New York over the weekend, bringing a special guest on stage to perform their song “Burnin’ Up”.

Former bodyguard Robert Feggans - also known as “Big Rob” - can be seen singing and dancing alongside Nick, Joe and Kevin.

The band have teased that other “very famous” guests will be joining them throughout their tour and the brothers also dedicated songs to their wives on Saturday night.

Nick is married to Priyanka Chopra, Joe to Sophie Turner and Kevin to Danielle Jonas.
