Posing in between his mom and his girlfriend Gigi Hadid, Zayn proudly shows off his bare head, while still sporting his trademark scruffy beard.
Trisha offered no explanation as to what prompted her son's drastic new look, simply captioning the photo with a series of love heart emojis.
Meanwhile, Gigi, 22, is seen beaming at the camera beside him, while his mom plants a sweet kiss on the side of her son's newly bald head.
His shaved head appears to have been an extremely recent development, as just two days earlier, Zayn was sporting a full head of hair in yet another photo posted on Trisha's Instagram.
