Kate Hudson wowed in a plunging copper-hued ensemble at the Glamour Women of the Year Awards held at Berkeley Square Gardens in London on Tuesday. Her date for the night was her stunner mom Goldie Hawn. Kate showed off major cleavage in the floor-length gown, according to Mirror UK.

Kate rocked a very 1970s vibe in the J. Mendel dress. The pre-fall dress from the label’s collection was cinched at the waist with a belt showing off her incredible figure. She added a touch of casualness to her dazzling ensemble by keeping her blond hair wept back into a messy and loose topknot.

She kept her accessories simple and minimum. Hudson carried a matching clutch and paired her dress with long earrings. Her makeup also consisted of a neutral palette with light pink lips. The star flashed a huge smile as she joined her famous mom outside. Hudson, who was awarded the “Glamour Entrepreneur of the Year” award thanked her mom for being her inspiration.

The mother-daughter duo posed for a photo together on the red carpet. Goldie was chic in a patterned black and white mini dress as her long blond hair fell loose around her shoulders and looked ageless next to her beautiful daughter. Their sweet mother-daughter outing came just one day after they attended Goldie's "Love-In For Kids" event as part of her charity, the Hawn Foundation UK. 

The 36-year-old actress shared a hilarious Instagram video, “Wish I Was Here.” It shows the mom of two smoldering in front of the camera as she sashays and flicks the front of her dress up, revealing a huge, long slit that parts to show her entire leg, pert posterior and her abs. As she continues swishing from side to side, her mom, Hawn, 69, is heard telling her that’s just what the dress should have done at the event.

The pair was meanwhile joined by a host of stars outside, from Amanda Holden and Kerry Washington, to Claudia Winkleman, Tess Daley and more. Amanda brought some color into the event as she smiled from ear to ear in a statement colorful gown. Showing off her slim figure, the 44-year-old opted for a one-shoulder floor-length patterned gown, and left the plunging gowns of "Britain's Got Talent" at home for the night.
