The starlet may have recently quit Made In Chelsea but she's already stepped back in front of the camera, making a cameo appearance in a short clip for ASOS.
The 90s-inspired video for 'Supersonic' - a tune performed by the ASOS House Band - sees the former reality star rocking loosely curled hair with a pinned back fringe.
She pulls her best pout while sporting a fierce studded bomber jacket and a black cami, adding a slick of pink lippy.
The song supposedly pays homage to Millie's fashion transition from West London 'It' girl to an edgy East Londoner, following her nuptials to her rapper beau.
And it seemed Millie enjoyed playing dress up for the video, saying: "I love experimenting with different styles, so creating my 90s-inspired look for the video was a lot of fun."
