Pete Davidson walks first red carpet in a year and a half after shutting down rehab rumor

Pete Davidson is back on the red carpet.

The comedian briefly posed for photographers Monday at the Broadway opening of “All In: Comedy About Love” by Simon Rich, which co-stars his friend and fellow “Saturday Night Live” alum John Mulaney.

An insider tells Page Six exclusively that Davidson attended the show with his mother, Amy Waters Davidson, and sister, Casey Davidson.

For his first carpet appearance in a year and a half, the stand-up comic wore a brown leather jacket, a black T-shirt, black pants and sneakers as well as an FDNY necklace honoring his late father, Scott Davidson, a firefighter who died in the 9/11 attack on the World Trade Center.

The outing came after a report that Pete, 31, had checked into rehab for the second time this year following a rumored romance with “The Bachelor” alum Maria Georgas.

However, sources insisted to Page Six that he had not entered treatment again, which he proved by attending a Brooklyn Nets game with his mom last month.

The “King of Staten Island” star, who has had a string of high-profile romances with stars including Kim Kardashian and Ariana Grande, shared in a recent interview that he does not want to be known as “this f–king loser who just dates people.”

“I just want to be known for doing good work,” he told W magazine.

“I want to be out there only when it’s [a] movie, stand-up, charity or business ventures. That’s when I want to be seen. I don’t want to be this f—ing loser who just dates people. That’s not who I am.”

Pete also has been honest about his issues with mental health and sobriety.

In July, the “Bupkis” star revealed the one drug he still could not kick after refraining from other substances.

“I can’t quit [weed] yet. It’s all I have left,” he told a crowd in Atlantic City, NJ, in July during his Rehab Tour.
