He's a looker! Jude Law's 17-year-old son Rafferty is ready for the spotlight. The actor's eldest child made his modeling debut during a DKNY menswear show in London on Sunday, June 15—and he fit right in.

All grown up, the tall blonde walked the runway in sleek black pants and a matching button-up. Clearly inheriting his famous father's handsome genes, he kept serious as he filed in on stage with several other male models in tow.

Rafferty is big brother to sister Iris, 13, and brother Rudy, 11, whom Law had with ex-wife Sadie Frost. The Sherlock Holmes actor shares daughter Sophia, 4, with ex-girlfriend Samantha Burke, too.

Law's offspring may be branching out, but another famous Brit's son has also decided to hit the catwalk—Brooklyn Beckham.

David and Victoria Beckham's 15-year-old son made his modeling debut on the cover of Man About Town magazine's Spring/Summer 2014 issue last April. Like Rafferty, Brooklyn gave his best pout as he showed off his steel-?blue eyes in the fashion photo shoot.
