Greek designer Di Petsa put motherhood at the center of London Fashion Week on Monday, September 21, with a surprise runway appearance by heavily pregnant Little Mix star Leigh-Anne Pinnock .

The 34-year-old modeled an ivory two-piece ensemble inspired by a goddess-like aesthetic, captivating fans who labeled her “art.”

The mood, however, changed dramatically during the finale, when liquid designed to resemble breast milk began squirting from Pinnock’s chest.

“Why, seriously?” one person asked, while another commented, “Just because you can doesn’t mean you should.”

Pinnock took to Instagram late Monday to share her experience walking the runway with her 9.3 million followers.

The singer expressed elation over making her modeling debut with Di Petsa, explaining that the milestone felt even more meaningful because she did it while pregnant.

“I don’t think I’ll ever forget this moment,” she wrote.

Pinnock then addressed the designer directly, thanking her for not asking her to make her journey into motherhood “smaller, quieter or more palatable.”
