Who is this model's very famous dad?

In news that will make you feel officially old, this young male model is the son of one of your favourite movie stars.

Who’s that model? It’s Rafferty Law. The 17-year-old son of Jude Law and Sadie Frost.

How is that possible?

Rafferty made his catwalk debut for DKNY in London on Sunday as part of the London Collections: Men’s Show. It’s his first catwalk show since he signed a contract with Select Model Management back in October last year.

Of course, his dad has had his turn at modelling, gracing a few ads for Dior back in the day himself (above, right).

Apparently Rafferty is quite the It Boy these days, often seen out in London with Kate Moss's little sister, Lottie. He's the oldest of Jude's three children with Sadie, his wife of six years. He has a little brother, Rudy, and a sister, Iris. Jude and Sadie split in 2003, and Jude went on to a famous affair with Sienna Miller, and then to have another baby, Sofia, from a fling with aspiring actress Samantha Burke in 2009.

We bet Jude's proud as punch that his boy is such a chip off the old block, but he and Sadie are obviously letting him run his own race - neither of them were in the audience when he made his catwalk debut.
