The power couple bought a $12 million house together before they were engaged.

Snapchat cofounder and CEO Evan Spiegel, 27, is one of the richest millennial billionaires in America, with a fortune around $3.4 billion.

In May, he married Miranda Kerr, an Australian supermodel and owner of cosmetics line Kora Organics. The 34-year-old is wealthy in her own right, with an estimated net worth of $45 million.

Like any good power couple, Spiegel and Kerr purportedly share interests in each others' endeavors. He's graced the cover of Vogue Italy, and she's active on Snapchat and has come to the defense of the company - and her husband - in interviews.

Here's how the newlyweds spend their billions.
