Chris Brown Performs at JAM'N 94.5 Summer Jam [Video]

Chris Brown worked up a sweat at JAM’N 94.5’s Summer Jam in Boston, sharing the bill with T-Pain, Lupe Fiasco, Waka Flocka Flame, Fabolous, DJ Khaled, Jeremih, and more.

“So about two years ago they weren’t f**king with me, look at me now,” said the blond singer after tearing off his American flag tank top and delivering his hit single to the packed house at Comcast Center.

He brought Big Sean to the stage for “My Last” and reprised his lap dance for a lucky lady in the audience. But he couldn’t leave without showing off some of his best moves as the DJ played LMFAO’s “Shots,” Beyoncé’s “Run the World (Girls),” Soulja Boy’s “Turn My Swag On,” Jay-Z’s “Public Service Announcement,” and more.

Check out some of the highlights below.
