Cut-out dresses were all the rage at London Fashion Week, and Amanda Holden and her daughter Lexi wore matching versions.

Amanda Holden and her daughter Lexi were photographed in the front row at a show during London Fashion Week.

Amanda, who just turned 52 in Dubai’s warm climate, celebrated the return of fashion designer Julien Macdonald to the stage on Sunday.

Models Winnie Harlow, Leomie Anderson, and Cindy Bruna walked the runway at the lavish Freemasons’ Hall in London for a fashion show that was a collaboration with Mexican designer Gabriela Gonzalez.

The judge on Britain’s Got Talent showed up to the fancy event in a stunning black gown with a lace bodice and a revealing cutout on the skirt.

She completed the seductive ensemble with a glittering clutch and silver jewelry to complement her signature blonde locks styled in bouncy curls.

Amanda looked as bronzed as ever as she posed with Lexi, 17, who was wearing a dress reminiscent of the 1920s flapper era and was accessorized with chains.

She looked radiant as she strutted down the red carpet, having completed her look with fresh, dewy makeup and silver jewelry.

In addition to Gemma Collins, Despacito’s Luis Fonsi, and Strictly Come Dancing’s Alja korjanec and Janette Manrara were also present.

Former Pussycat Doll Ashley Roberts, who was photographed alongside the mother and daughter, was dressed to the nines in a sleek black minidress and smoky eye makeup.

In one example of the fanfare surrounding Lexi and Amanda, a user on Instagram wrote: “Beautiful like your mummy.”

“That photo you look just like your stunning Mam,” another said, as a third added, “Like your mum….endless legs!!!!”

Leomie Anderson, a British model, opened the show wearing a black sequined bodysuit with cut-out details and exaggerated shoulders, and she walked to the recently controversial hit Unholy by Sam Smith and Kim Petras.

The Welsh designer’s signatures, such as bodycon silhouettes, bejeweled minidresses, metallic gowns, mesh catsuits, and masses of sequins, were prominent in a gothic glamour inspired collection.

Many of the minidresses had drapes that brought to mind the silver dress that Julien Macdonald is best known for designing for Paris Hilton’s 21st birthday party.

The veteran of London Fashion Week is a go-to designer for red carpets, and Gisele Bundchen and Bella Hadid have recently been spotted in his ultra-glamorous gowns.

Beyonce, Kylie Minogue, and Jennifer Lopez are just a few of the famous singers who have been outfitted by the 51-year-old designer.

Last week, Amanda celebrated her birthday by posting a cheeky bikini photo from her party to Instagram with the caption: “52 today -grateful to be alive and happy with people I love.”

Alan Carr was just one of many who stopped by to wish the former EastEnders actress a happy birthday in the comments section: “Happy Birthday my darling!! X.”

“Happy birthday,” wrote Sam Faiers alongside a love heart, as Ashley Roberts added: “Legend. Happy birthday sister!!!!!!”
