It’s the busiest shopping day of the year, and this morning the Jonas Brothers were on hand at “Good Morning America” encouraging all of the Black Friday shoppers to buy their new book.

Nick, Joe, and Kevin were spotted leaving their swanky New York City hotel and arriving at CBS Studios for their GMA appearance to promote “Burning Up: On Tour with the Jonas Brothers.”

Yesterday, the JoBros spent their Thanksgiving holiday entertaining a sell-out crowd of 63,523 at the Dallas Cowboys/Seattle Seahawks football game halftime show.

They performed “Lovebug” and “Burnin’ Up” during their set, which also kicked off the Salvation Army’s Red Kettle Christmas Campaign.

Prior to their performance, Nick told press, “We’re excited and honored to be participating in The Salvation Army’s Red Kettle Campaign, and to help this worthy organization improve the lives of others.”
