Jason Derulo, Nelly, Mike Posner, Auburn and Far East Movement were also on hand to treat concertgoers with their live performances.
Following Q102 show in New Jersey and Z100 bash in New York City among other mega concerts, another Jingle Ball to celebrate the holiday was held by B96 radio station in Chicago, Illinois. Justin Bieber pumped up the crowd with his energy performances, and Bruno Mars melted girls' hearts with his buoyant voice.
Wearing all-white outfit matched with black fingerless gloves, Bieber launched some of his popular songs like "One Less Lonely Girl" and "Baby" for the screaming fans flooding the Allstate Arena on Saturday, December 11. Mars going simple with a hipster hat and plaid shirt played his guitar throughout the set which included hit single "Just the Way You Are".
The other performers at that night were Jason Derulo, Nelly, Mike Posner, Auburn and Far East Movement.
