We're not talking about any old red carpet event either. Both ladies upped their beauty game for the most prestigious film festival in the world, the 66th Cannes Film Festival!
Side partings all-round...
Both Barbara and Doutzen rocked a side parting which really helped to show off their equally impressive make-up looks.
Doutzen's soft smoky eyes smouldered beautifully beneath her super-sleek hair whilst Barbara's bright orange eyeshadow added a bright pop of colour to her look.
Extraordinary oil, extraordinary hair?
We have a sneaking suspicion that Doutzen and Barbara keep their locks so sleek with the help of some hair oil. Hair oil is brilliant for all kinds of reasons.
For instance, it nourishes hair, keeps it sleek and smooth, protects it during heat treatments, helps to keep hair hydrated and, on top of all that, it smells fantastic.
No wonder these ladies and their long hair look so good!
We just can't decide which look we like best. Help us out by casting your vote above! Who will come out on top?
