Rich people. They're not like us. Take, for example, Anne Wojcicki, impending ex-wife of (dreamy) Google cofounder Sergey Brin. None too thrilled about seeing her husband leave her for a 26-year-old Google Glass marketing manager, the newest First Wives Club nominee had a helluva party the other night to celebrate her newfound singlehood.

Leah Garchik has the details:

But on Alcatraz, Anne Wojcicki, estranged wife of Google co-founder Sergey Brin, threw a party to celebrate "freedom," it said on the invitation. Perhaps this had to do with the August announcement that after six years of marriage the couple were living apart. It was said at the time that he was having an affair with Google Glass marketing manager Amanda Rosenberg. ("Sleeping her way to the top" was how one British newspaper described the Other Woman, but in light of accounts of her repeatedly texting him via Google Glass, this might be amended to "seeing her way to the top.")

Exclusive access to Alcatraz Island costs around $20,000. Around 100 people, Garchik goes on to report, attended the fete.

Brin and Wojcicki, both 40 with two kids, have been living apart for much of 2013. A spokesman for the couple told AllThingsD back in August, “[T]hey have been living apart for several months. They remain good friends and partners."
