As billionaire and former New York City mayor Michael Bloomberg continues (opens in new tab) his late-stage campaign for president in 2020, he's been on the campaign trail with his current partner Diana Taylor. She is not the mother of his two kids: Bloomberg was only married once, to Susan Brown (opens in new tab). The two split in 1993, but if reports are to be believed, they still have a more-than-cordial relationship. The pair are, in fact, called "best friends" by those closest to them. Here's what we know about Brown, her union with Bloomberg, and where they stand now.

Bloomberg was married to Susan Brown between 1976 and 1993.

Susan Brown (maiden name Meyer) had been married before and divorced, according to the wedding announcement in the New York Times (opens in new tab). She'd attended school in York, England and Neuchatel, Switzerland. The two have two children together, Georgina and Emma. Apparently they disagreed, often, about how much time he was spending away from his family.

"They were not getting along because their lives are not compatible," Emma explained. "My mother doesn't want to be social all of the time. She was perfectly happy to curl up with a book and not go out all week." But the pair remained friends after the divorce—Brown and her then-boyfriend campaigned for her ex and, as of 2001, were still celebrating holidays together.

Bloomberg also continued to support Brown after the divorce. In 2012, the New York Times (opens in new tab) reported:

"In 2011, Mr. Bloomberg helped his ex-wife, Susan, with at least two financial transactions: He provided a bridge loan of more than $500,000 so she could buy a new apartment, while she waited to close on the sale of her previous one, and he transferred more than $500,000 into a trust in her name."

According to Emma, "My parents are best friends...Nobody understands that until they actually see it." She was so positively impacted by the situation that she referenced it in her college essays, calling it "one of the best things that ever happened to me."

He's been with Diana Taylor since 2000.

The couple, who have been together for 20 years, met at a business lunch (opens in new tab), and he asked her out at a restaurant later. She's worked on Wall Street since the 1980s, was appointed New York state’s superintendent of banks in 2003, and even had fleeting political aspirations of her own. “Her famous boyfriend may be the least interesting thing about her,” said Anna Wintour (opens in new tab). “She’s intelligent, independent—and completely her own person. Michael is lucky to have her.”

They're not married, and don't seem to have any plans to be. Taylor says there really isn't a word for what they are—partner seems to be the closest. She's a "step-whatever...friend" to his kids, and fierce supporter of his political aspirations.
