These two are such an awesome mother-daughter team! Kate Hudson brought her mom, Goldie Hawn, with her as her date to Tuesday, June 2's Glamour Women of the Year Awards in London, England. But judging by a hilarious Instagram video, the most fun was had once the celebrity duo got back to their hotel room for an afterparty!

Hudson, who was awarded the Glamour Entrepreneur of the Year award, and thanked her mom Hawn for being her inspiration, wowed on the red carpet, with her sexy, super-low cut gown that showed off her cleavage. But while other celebrities like Rosie Huntington-Whiteley and Ellie Goulding showed off their legs at the star-studded event, Hudson's famous gams remained hidden away.

At least, that is, until her own private afterparty!

In a video the Wish I Was Here actress shared via Instagram, the 36-year-old mom of two literally smolders in front of the camera as she sashays and flicks the front of her dress up, revealing a huge, long slit which parts to show her entire leg, butt, and stomach.

As she continues sexily swishing from side to side, her mom, Hawn, is heard telling her that's just what the dress should have done at the event!

"Honey, the dress has to do that. Unfortunately there was no wind machine," Hawn says, between hysterical bouts of laughter.
