On Tuesday, the Spice Girl turned fashion mogul, 46, posed with her youngest son Cruz in matching white bathrobes, with both beaming brightly.

“Apparently my mum does smile 😃❤️,” the 15-year-old captioned their twinning moment on Instagram.

But the designer’s husband David couldn’t resist poking fun at her blindingly bright grin.

“How white are mums @victoriabeckham teeth ? 🦷 it’s Ross from friends 😂,” the former professional footballer, 45, commented on his son’s snap.

In an unforgettable episode of the hit NBC sitcom, David Schwimmer’s character leaves on a set of whitening strips for far too long, to the horror of his pals (and his hot date).

Beckham has referenced her reticence toward toothy grins in the past. “I’m smiling on the inside. I feel that I have a responsibility to the fashion community [to stay stoic],” she told Vogue’s “73 Questions” in 2015.

But in a 2019 interview with Glamour UK, the star hinted that we may be seeing more of her pearly whites in the future as she becomes more self-assured.

“I want to be honest. In the past, I’ve probably hidden behind my armor — the not smiling publicly, for instance. There’s less of that now,” Beckham confessed.
