Former New York City Mayor and Bloomberg founder Mike Bloomberg and Diana Taylor hold a private wedding at their Upper East Side home
On November 9, 2026, former New York City Mayor and Bloomberg founder Mike Bloomberg and his long-time partner Diana Taylor (Diana Lancaster Taylor) held a small private wedding at their home on Manhattan’s Upper East Side. A Bloomberg spokesperson said in a statement posted on Bloomberg’s X account that the two formally married after 26 years of knowing each other, and that family members, including Bloomberg’s daughters Emma and Georgina, attended the ceremony.
The spokesperson said the two first met in 2000, during Bloomberg’s first campaign for New York City mayor, when they became acquainted by sitting next to each other at a Citizens Budget Commission meeting. Taylor, a former superintendent of the New York State Banking Department, often accompanied Bloomberg in an unofficial capacity to public events during the 12 years he served as mayor.

Diana Lancaster Taylor was born in 1955 and graduated from Dartmouth College and Columbia University, holding an MBA and a master’s degree in public health. She worked on Wall Street early in her career, and from 2003 to 2007 served as superintendent of the New York State Banking Department. She later served for many years on nonprofit and corporate boards, including as chair of the board of the New York City Ballet, and for Citigroup, Sotheby’s, and Brookfield Properties. Bloomberg married his former wife Susan Brown in 1975, divorced in 1993, and they have two daughters, Emma and Georgina; Taylor also previously had a marriage, and neither side has any children together.
After Bloomberg and Taylor met, they quickly moved in together in an Upper East Side townhouse and formed a stable public partnership during Bloomberg’s three mayoral terms. Taylor often accompanied him to campaign and city government events, including a “Women for Mike” rally during the 2020 presidential primary; in media interviews, she clearly said she prioritized her professional identity rather than the label of “first lady.” The two long maintained a de facto partnership, and in a 2020 interview with Gayle King, Bloomberg said neither side had plans to change the status quo.
Unlike many public figures who marry during political peaks, Bloomberg and Taylor chose to officially register their marriage after both had left major public office and after their relationship had lasted for more than a quarter of a century. Taylor’s independent record in banking regulation, corporate governance, and arts institutions has kept her professional trajectory relatively separate from Bloomberg’s political identity; this arrangement contrasts with the pattern in which some political partners are quickly brought into family roles during campaigns.
This marriage turns their long-term de facto partnership into a legal spousal status, mainly affecting internal family legal and inheritance arrangements rather than their publicly known business or charitable paths. Bloomberg’s two adult daughters attended the wedding as family members, showing the existing family structure’s acceptance of this decision; for Taylor, the formal marriage does not change her existing board positions or professional identity, but it provides a clearer legal framework for her role in Bloomberg’s public life over the years.

A 26-year de facto partnership completed its transition into marriage after leaving public office; what changed was legal status, not the established life and career trajectory.
An unofficial partner role can sustain a public role over the long term; formal marriage is not necessary, but it can provide clear boundaries for inheritance and family arrangements.
