Carole Radziwill says she wouldn’t have recognized Harry Styles before viral wedding photo

Carole Radziwill claimed she wouldn’t have recognized Harry Styles before they were snapped together in a viral photo from a friend’s wedding.

The “Real Housewives of New York City” alum detailed the singer’s chivalrous act of him taking her arm on Tuesday’s episode of Dorinda Medley and Kiki Monique’s “Reality Checked” podcast.

Radziwill, 62, explained that she “didn’t know” Styles, 31, was behind her and close pal Cassandra Grey when they were climbing up a set of stairs at the Parisian nuptials of Charles Porch and Robert Denning.

“Harry came over,” Radziwill recalled. “He’s really, actually, such a lovely person and if I didn’t know he was going to be at the wedding … I don’t know if I would’ve recognized him.”

The Bravolebrity described the “As It Was” singer as being “lovely.”

“He said, ‘How can I help you?’ … I was like, ‘You know, take my arm.’ And he did,” she said. “And it was really sweet.”

Medley jumped in to call the moment “a fairytale,” to which Radziwill replied, “He was a prince.”

Radziwill admitted that she didn’t know the photo was ever going to be shared online.

“Cassandra had posted when we were on the plane. I was sleeping and I didn’t realize she was posting the photos,” Radziwill said. “I wasn’t going to post anything.”

When she finally woke up upon landing after a six-hour flight, Radziwill said her phone was “blowing up.”

“I’m just like … half asleep, opening up my phone. My phone was blowing up. It was nuclear,” she said.

Despite their special bonding moment, Harry did not respond to being tagged in the image.

“Well, maybe he will. I mean, it was funny,” Radziwill said.

“I mean, after two days of it, to be honest, I wanted it to all go away,” she continued. “[But] I was kind of flattered that a lot of people were like, ‘Yeah, I ship that … I support it.’”

As Page Six reported, Grey posted a 20-slide Instagram post on Sept. 1, including a snap of Harry assisting Radziwill up the stairs at the starry wedding.

Grey explained what happened in the caption, writing, “I saw @caroleradziwill struggling to get her rather large @giambattistavalliparis dress up the grand stairwell.”

She joked that she took her iPhone out to “document what could have been fashion Parisian castle roadkill.”

“Then a stranger to Carole and I, a handsome @harrystyles, seemingly out of nowhere, graciously lent her his arm like Cinderella’s prince,” she gushed.

Just days prior, Styles was spotted smooching Zoë Kravitz on a London date night. They have been spotted showing PDA on several occasions ever since.
