Inside Andy Cohen’s star-studded ‘Watch What Happens Live’ 15th anniversary party

More than a dozen Bravolebrities came together for Andy Cohen’s party celebrating the 15th anniversary of “Watch What Happens Live” in New York City on Wednesday night.

Guests at Boom at the Standard High Line hotel included Craig Conover and Austen Kroll from “Southern Charm”; Kyle Cooke, Carl Radke, Amanda Batula and Paige DeSorbo from “Summer House”; Teresa Giudice, Melissa Gorga and Margaret Josephs from “The Real Housewives of New Jersey”; Scheana Shay from “Vanderpump Rules”; and Heather Gay and Whitney Rose from “The Real Housewives of Salt Lake City.”

In the middle of the celebration, Cohen jumped on top of the circular bar to share a few words, thank the attendees and even tease Page Six.

“The Bravo folks that are here are members of our ’15-Timers Club,'” he said. “We invited everyone on Bravo who has been on the show 15 times or more to come, and we’re so happy that you are all here, and you are the bread and butter of what we do, quite literally, and we are so honored you keep coming back for more.”

Cohen, 56, gave a special shout-out to Giudice, 52, as the “most common guest” with a whopping 42 appearances since his late-night talk show premiered in July 2009.

“My guys Austen and Craig, Kyle and Scheana, I’ve given you guys more crap on live television, and you have such great senses of humor, and you’re just great sports, and we love having you,” he said.

Cohen also thanked his executive producer, other “WWHL” staples and his 5-year-old son, Ben, who was in attendance.

The host then joked that he was going to share some stories from his days partying at Boom, “but Page Six is here, so I can’t.”

“I’m so excited that we’re here, and we hope to be here for as long as you will have us at the Boom Boom Room and on Bravo. Thanks, everybody! Cheers to 15 years! Unbelievable!” he concluded his speech while raising his glass along with all his guests.

Stars sipped on Champagne and custom drinks playfully called the Clubhouse Fresquila, Truth or Gin and It’s Scotch-Ski Time in addition to enjoying mini flatbreads, charcuterie and a massive cake.

As the night continued, Bravolebrities mingled with one another — but not everyone.

Notably, Conover, 35, and Cooke, 41, were not seen socializing with each other amid the strain in their friendship over competing business ventures.

However, Cooke was seen hugging and chatting with Conover’s co-star and close friend Kroll, 36, as well as the Sewing Down South owner’s girlfriend, DeSorbo.

Cooke’s co-star and fellow Loverboy investor Radke was also spotted chatting it up with Kroll.

Meanwhile, besties Batula, 32, and DeSorbo, 31, did not seem to let their respective partners’s issues come between them, as they hung out together most of the night.

Estranged sisters-in-law Giudice, 52, and Gorga, 45, also stayed on opposite sides of the room, keeping their promise not to speak to each other following their falling out last year.

Even the Gay Shark from “WWHL” was in attendance. Charles Sykes/Bravo Several Bravolebrities put their feuds aside to have a joyous night. Charles Sykes/Bravo The night ended with Cohen cutting into a custom cake. Charles Sykes/Bravo

Gorga brought her husband and Giudice’s brother, Joe Gorga, who made the most of the night by getting on top of the bar with Cohen to take a shot with the man of the hour and other Bravolebs.

To top off the night, the famous Gay Shark from “WWHL” danced and took photos with all the guests.

“Watch What Happens Live with Andy Cohen” will host an hour-long primetime special to honor the milestone anniversary on Sunday, June 30, at 9 p.m. ET on Bravo.
