They grow up so fast: See Jude Law's daughter Iris in her first modelling campaign

The next big thing?

It's hard to believe that one of our favourite heartthrobs, Jude Law, has a daughter old enough to be a model - but 15-year-old Iris is already one of the faces of a major fashion campaign.

Following in the footsteps of her brother Rafferty, who has modelled for DKNY, Iris stars alongside model Evangeline Ling in the shoot for Illustrated People's hand-designed printed pyjamas.

The PJs have been created with London stylist Violetta Fancies You, with the creative director none other than Phoebe Lettice Thompson (remember her from Made In Chelsea?).

In the shoot, Iris is seen with dark plum lipstick, Princess Leia-style buns in her hair and a pair of dark silk pyjamas. The PJs in question say 'I would rather be sleeping' on the back, while others in the collection include a camouflage-style blue pair and a pale pink pair with colourful detail.

Who knew sleepwear could be so chic?

She has already built up quite the following on Instagram, with nearly 5,000 followers and several pictures of her looking like a chip off the old block - lest we forget that her father is Jude and her mother is Sadie Frost.

With rising stars like Lily Rose Depp, Kaia Jordan Gerber and now Iris Law on the scene, are these celebrity daughters going to one day be as famous as their parents?

There are rumours that Kate Moss's daughter Lila is going to follow her footsteps into modelling, and you just need to look at the likes of Immy Waterhouse and Bella Hadid to see that modelling runs in the blood of famous families.
