Guess the Celebrity Brother!

Can you figure out who this sibling is? He's got two hip brothers and he's an uncle to a couple of really cute kids

In addition to sharing similar facial features with his two younger celeb siblings—and an obvious affinity for porkpie hats—this music producer/DJ also cofounded a hip clothing line with them.

While he may not be as well known as his twin brothers, he can at least take comfort in the fact that even their fame has been quickly overshadowed by his adorable niece and supercute nephew.

So who is he?

It's Josh Madden!

The brother of Benji and Joel Madden was spotted at New York City hot spot Greenhouse on Tuesday night, catching a performance by DJ Premier.

Luckily for Harlow and Sparrow, coolness really does run in the family.
