Sergey Brin’s new girlfriend

Sergey Brin

On Aug. 29, news broke that Google co-founder Sergey Brin, 40, had separated from his wife, Anne Wojcicki, 40, and that he had a new girlfriend, Amanda Rosenberg, 27, a marketing director for Google Glass. Brin’s Jewish parents left the former Soviet Union in 1979, where anti-Semitism had impeded their respective academic careers.

The Stanford-educated Brin wed biologist Wojcicki in 2007 and the couple have two children. Neither Brin nor Wojcicki (whose mother is Jewish) are religious, but they did have a chuppah at their wedding and Brin stepped on a glass.

Sources say Brin, said to be worth $24 billion, separated from his wife before he began dating Rosenberg. According to the U.K.’s Daily Telegraph, Rosenberg, whose father is British, worked for Google in London before moving to San Francisco last year. In her blog, Rosenberg says she is “part of the master race that is the Chinese Jew or Chew, if you will. Born in Hong Kong but bred in the UK. A misanthrope who’s bad at maths, so I got the worst of both worlds.’ ”

Arquette marries a mensch

Actress Rosanna Arquette, 54, married investment counselor and manager Todd Morgan, 65, on Aug. 18 in a private ceremony. Attending were family and a few friends (reportedly including Barbra Streisand, 71). Arquette is the daughter of a Jewish mother (whose own mother was a Holocaust survivor) and a non-Jewish father. She has always been the most “Jewish-identified” of the Arquette acting siblings (her brother David identifies as a Christian; her sister Patricia is unaffiliated). This is Rosanna’s fourth marriage (two lasted a year). Her six-year marriage to hip restaurateur John Sidel, 55, produced her only child, daughter Zoe, 18.

Morgan is a former Goldman-Sachs banker who moved to Los Angeles in the late ’80s and founded a wealth management firm, which he still heads, that was a pioneer in deftly and conservatively investing the money of the very rich. About 20 percent of Morgan’s clients are celebs (including Streisand), and his firm now manages more than $5 billion.

Morgan is a member of two Los Angeles synagogues and served as head of the Jewish Federation of Greater L.A. in 2001-2002. In 2011, he was honored with its humanity award for establishing the Morgan Aging with Dignity Fund, which helps L.A.-area Holocaust survivors. Morgan became interested in Jewish issues in the ’80s and began aiding Soviet Jews, some of whom he visited in Israel.

The Monaco royal circus

I expect many have already read that Princess Charlotte, 27, the only daughter of Princess Caroline of Monaco, is engaged to marry comedic actor Gad Elmaleh, 42, and is carrying his child. If you’re surprised that a fancy-shmancy Catholic princess would marry a French Sephardi Jewish actor — well, you don’t know much about the romantic relationships of Monaco’s royal family. Elmaleh, born in Morocco, is popular with French and Arab audiences. And, by the way, he already has one child born out of wedlock.

In some sense, he will fit right into the Grimaldi family. Princess Caroline’s aunt, Princess Antoinette, had three out-of-wedlock children with her married lover between 1947 and 1951; Caroline’s paternal grandmother, Princess Charlotte, turned her Paris-area estate into a refuge for ex-convicts and took a famous former jewel thief as her lover; Caroline’s sister, Princess Stéphanie, was long involved with a married elephant trainer — her second ex-husband is a Portuguese acrobat — and she has a child with another man she never married; Caroline’s brother, the reigning Prince Albert, has two out-of-wedlock kids: one by an American waitress and another with an Air France flight attendant.
