Justin Theroux's Hot Younger Brother Sets Internet, Hearts Aflame

Yesterday the paparazzi captured actor Justin Theroux taking a stroll in New York City with his younger doppelganger. Almost instantaneously websites and blogs were alight with questions about this handsome younger version of one of our favorite actors.

It turns out Justin’s twin is actually his younger brother, Sebastian, 24. Who knew Justin Theroux had such a hot younger brother and where has he been hiding him?

The two men were dressed in nearly identical outfits, sporting black pants, black leather jackets, hoodies, combat boots, jet-black hair, and devilish grins.

Rumors have been swirling that Theroux’s wedding to Jennifer Aniston is imminent, and the appearance of Justin’s brother had tongues wagging that he could be playing the part of best man at the ceremony. The Sun, however, seems to think Justin’s best friend, actor Ben Stiller, has already reserved the coveted role.

According to the Daily Mail, Justin and Jennifer are planning to tie the knot in a low-key affair in Hawaii in just a few weeks where she has a little house in Kauai. Ben Stiller also has a house in Hawaii so that could serve as the potential venue.

Celebitchy seemed to think the matching brothers were worthy of an LOL, but we’re with New York Magazine on this one: with one Theroux brother off the market, how lovely to know there’s a younger one still potentially up for grabs!

Perhaps Justin has been keeping him out of the limelight since Sebastian just recently transitioned from that awkward adolescent stage to full blown babe. Check out this adorable photo of the brothers from a few years back.

There’s pretty much nothing on the Internet that indicates what Sebastian Theroux does for a living or where he lives.  We do know that the siblings come from a very distinguished family. Their mom is a journalist for the Washington Post and their dad is a corporate lawyer. They are the nephews of writers Paul and Alexander Theroux and the cousins of filmmakers Louis and Marcel Theroux.

But we’d love to know more about Sebastian—specifically his relationship status. Does he want to marry us in Hawaii? Ok, who knows what he’s into. Let’s just say we’d definitely purchase a Theroux brothers shirtless calendar.
