MARIAH Carey just can’t keep herself covered up.

The singer, 46, has again suffered a wardrobe malfunction involving her boobs — this time, at Vanity Fair’s Oscars after-party.

James Packer’s former fiance wore a Philipp Plein animal-print gown with a plunging neckline that showed off her ample cleavage. The only problem was that it also exposed the top of her right nipple.

The fashion at the Oscars afterparties, particularity Vanity Fair’s, almost overshadowed the Academy Awards itself, with stars taking style risks when the pressure was off.

Carey posed for photographs on the striped carpet at the VVVIPbash, held at the Wallis Annenberg Centre for the Performing Arts in Beverly Hills.

Unlike Mariah, some Hollywood stars actually knew how to dress themselves without having an X-rated peep show at the after-party, where the dress code was definitely “formal” (implying no visible nipples).

Miranda Kerr, Jennifer Aniston, Justin Theroux, Vin Diesel, Kate Bosworth, Oscars host Jimmy Kimmel, Scarlett Johansson, Demi Lovato, Reese Witherspoon and Jessica Alba also partied at Vanity Fair.

Jessica Biel looked every inch the movie star despite not really being in any Oscar-worthy films.

Thigh splits were a key look, with actors showing off their toned legs and strappy shoes, along with lots of cleavage, sideboob and fake tan (and in Mariah’s case, nipple).
