See the two awkward multimillionaires cheesing in button-ups. Instagram's 26-year-old co-founders Kevin Systrom (center top) and Mike Krieger (top right) have Mark Zuckerberg's money; Facebook recently acquired the photo-sharing app for $1 billion.

Scratching that new allowance itch, Systrom and Krieger partied in Las Vegas, first dining at Botero at the Wynn with Jesse Waits (left bottom), the club managing partner at Encore’s XS nightcluband DJs Deadmau5 (top left) and Avicii (bottom right). They then traveled to XS. Reportedly they ordered a bottle of Armand de Brignac "Midas," the world's biggest bottle of champagne. Cost? $150,000.

Which means absolutely nothing to their bank accounts now.
