Michael Bloomberg and Diana Taylor were spotted celebrating tying the knot after more than 25 years with an intimate dinner Monday at luxe Italian restaurant Gabriel’s on Central Park South. 

We hear the pair — who were wed earlier in a private ceremony at their home on the Upper East Side — were joined by Bloomberg Philanthropies CEO Patti Harris and her husband Mark Lebow.

Harris also worked for the former three-term mayor during his administration, as deputy mayor and then as New York’s first female first deputy mayor.

A spy tells us the newlyweds “were dressed up and looked happy.”

“At the end they did toasts,” said the witness. “It was a joyous occasion.” 

(We hear Bloomberg did not drink any alcohol, but others in the group toasted with bubbly.)

They also got well-wishes from a fellow high-powered patron: former CIA Director George Tenet was spotted congratulating the couple. 

Bloomberg, 84, and Taylor, 71, were wed earlier in the day in front of his daughters Emma and Georgina. They also held a lunch with a dozen close friends and family. According to the New York Times, he also popped by his offices. 

The pair met 26 years ago after a chance seating arrangement.

“The longtime couple exchanged vows today in a small, private ceremony at their home on the Upper East Side, joined by family, including his daughters, Emma and Georgina,” Bloomberg’s spokesperson announced.

“The two first crossed paths when they sat next to each other at a Citizens Budget Commission meeting while he was first running for mayor.”

Bloomberg has been dodging the question over whether he would pop the question for over two decades. 

During a 2011 appearance on “The View,” Joy Behar — who had recently wed Steve Janowitz —  teased, “Maybe you’re next,” to which he curtly responded, “Let’s talk about something [else].” 

During his failed 2020 presidential run, Taylor told The Washington Post she hated the term “gal pal,” and said, “Nobody’s come up with the language around what we are.” 

Ivy Leaguer Taylor — who functioned as NYC’s unofficial First Lady during his administration, attending events and galas — has worked on Wall Street and was superintendent of banking for New York State during the Gov. George E. Pataki administration.

She was approved as chair of the New York City Ballet’s board of directors in 2021. The couple attended this year’s gala at Lincoln Center together. 

Bloomberg was previously married to Susan Brown in 1976. They split in 1993.

Taylor was also previously married.
