Google co-founder Sergey Brin splits from wife Anne Wojcicki

SAN FRANCISCO -- One of Silicon Valley's power couples has separated.

Google co-founder Sergey Brin is living apart from wife and 23andMe co-founder Anne Wojcicki, according to a report in technology blog All Things D.

Brin and Wojcicki, both 40, have been married for six years and have two children. The couple have been living apart for several months, a spokesman for the couple said.

"They remain good friends and partners,” the person said. They are not legally separated.

It's unclear if the couple will reconcile because, according to the report, Brin is dating a Google employee.

The split will reportedly not have an effect on Google even if the couple divorce. Brin and Wojcicki have a prenuptial agreement, All Things D said.

Brin is one of the world's richest men and is currently worth $22.8 billion, according to Forbes.

He also has many business entanglements with Wojcicki. He, Google and Google Ventures have all invested in 23andMe, which sells DNA test kits. 

The couple also are involved with the Breakthrough Prize Foundation with another Silicon Valley power couple, Mark Zuckerberg and Priscilla Chan. They also buy and renovate property in downtown Los Altos, Calif., near their home.

A spokesman told All Things D that Brin and Wojcicki would continue to work on these projects together.

Perhaps the stickiest situation: Susan Wojcicki, Anne's sister, is a top executive at Google.

The stunning revelation sent shock waves through Silicon Valley, where the couple have long held a high profile. 

The All Things D scoop was soon trending on Twitter and TechMeme. Tech writer Jessica Roy commented on Twitter: "Just gasped so loud I scared my cat."
