Mosque foes recently started a boycott of Bieber after he made comments in support of the mosque project in an interview with Tiger Beat, a teen fan magazine, Sullivan told WYNC earlier this month. Now, his 8-year-old daughter and 11-year-old son have been banned from attending Bieber performances.

“I informed them, ‘Hey guys, guess what? Justin Bieber spoke out for the ground zero mosque,” Sullivan explained to Salon in an interview. “My little girl took down his poster and said she didn’t want to have nothing to do with him anymore. These are my kids. They’re living this thing.”

OK, that is the most shifty, brilliant way I ever heard to convince your eight-year-old to stop lip-syncing Justin Bieber hits around the house.
