Rihanna stole the show at Sunday night's Grammy Awards, ignoring the alleged ban on sheer see-through clothing by flashing her nipples on the red carpet.

The pop beauty waltzed down the press line in a stunning silk chiffon red frock, with her breasts clearly but subtly visible, the Sun reported.

Her risque get-up comes after a leaked email claimed that Grammys bosses had imposed a ban on thongs, exposed nipples, bum crack, sideboob and underboob.
