Nervous execs have made curvy Katy Perry sign a contract to rein in her boobs at the Super Bowl halftime show!

Katy – whose “Sesame Street” gig was cut in 2010 when her jiggle was judged too much for Elmo to juggle – has been ordered to contain her rack.

NFL and NBC execs are terrified Katy might re-enact Janet Jackson’s infamous “wardrobe malfunction,” said a friend.

“She’s been warned not to flash the flesh, show off her cleavage or do anything provocative,” added the friend.

And she’s had to sign a contract agreeing to the terms.

“It’s going to be a big challenge for Katy because she doesn’t know if she’ll be able to contain her curves,” dished the pal.

“She says she’s going to have to strap down her boobs underneath her costume, or even perform bandaged up like an Egyptian mummy!”
