NEW YORK, Sept. 10 (UPI) -- Justin Bieber made a surprise appearance during CBS' Fashion Rocks, only to get booed as he performed a strip tease to promote Calvin Klein underwear.
"To introduce our next performance which features the latest looks from Calvin Klein jeans and underwear, we have two of his very close friends. Let's hear it for supermodel Lara Stone and Justin Bieber," host Ryan Seacrest said 90 minutes into the show.
