Ananova:

The fetish shop that sold Janet Jackson her Super Bowl outfit are furious over her boob flashing stunt.

DeMask, of Manhattan, New York, say it made it look as if her £140 bustier was flimsy, reports the New York Post.

Justin Timberlake tore off part of the bustier, exposing her breast, after singing the words: "I'm gonna have you naked by the end of this song."

The stunt, during a half-time duet, has caused a storm in the US but DeMask are more concerned with their reputation.

Manager Sam Hill said: "There's no way it would have ripped that way. We're known for putting together solid, long-lasting pieces."

She wants Jackson to own up to altering the top for the stunt which was originally billed as an accident.

"They took off the studs that kept the cup in place and replaced them with snaps so the top could just come off," she said.

"It would have looked like Justin was assaulting her if he'd tried to rip it off before it was modified. It's really easy to modify rubber. It's not rocket science."
