On Monday Nicki Minaj launched her new Nicki Lipglass for MAC cosmetics at the Selfridges department store on Oxford Street, keeping her bootilicious assets covered.

Yet last night the US rapper, 29, stepped out of her London hotel in a very revealing bejewelled bra-let!

Granted she did wear a denim jacket on top but that didn’t stop Nicki’s busty chest from making a special appearance.

Her poor bra looked strained under the pressure. Could have very nearly been a wardrobe malfunction.

What a nightmare that would have been! (Halloween pun intended)
