Demi Moore's daughter Rumer Willis suffered an embarrassing wardrobe malfunction at a red carpet event in Los Angeles on Tuesday (22Apr14) when she flashed her crotch in a revealing skirt.

The actress, whose father is Bruce Willis, was posing for photographers at the Elle Women In Music event in a knee-length black skirt, which was slashed along the leg.

The gaps in the fabric left Willis exposed, and fans could clearly see her pink underwear.

However, the 25 year old seemed unaware of the fashion faux pas as she tweeted throughout the event and posted pictures of her pals.

She wrote in a post on Twitter.com, "Love getting my girls together in one place. Thanks Elle Magazine."
