Katy Perry suffered an embarrassing wardrobe malfunction with her daring dress at an Oscars party on Sunday night (26Feb17).

The Chained to the Rhythm star arrived at the Vanity Fair party with writer pal Derek Blasberg before meeting up with her beau Orlando Bloom, who came along later.

When pictured from the front, Katy, complete with newly blonde-bobbed hairstyle, looked flawless in a bronze-coloured sequinned Jean Paul Gaultier dress from the couture house's Fall/Winter 2016 collection.

However, in a picture taken of the star from behind, in which she is watching the annual Academy Awards on a TV next to James Corden, the singer's bottom was exposed as a strategically-placed mesh insert between the top half and the skirt of the dress gave way.

Eagle-eyed Twitter users were quick to point out the flaw in Katy's dress, with one user tweeting: "I'm confused by the back of the dress @katyperry," and another user, writing, "um someone at VF needs to go help katy perry with her dress?..."

While it looked as if the singer's dress had ripped, it appeared to be a design flaw that left the Roar singer somewhat exposed, with her zip just about maintaining her modesty.

Katy recovered in time to take part in the publication's portrait session, which is taken annually during the afterparty.
