'RHONY': Jenna Lyons Recounts a Mortifying, Stocking-Ripping Run-In with an A-List Actor

"My coat is dragging on the steps behind me and someone steps on it. I go head-first like a rocket!” Jenna cringed as she recalled slipping down a steep hill before her celebrity helping hand

Jenna Lyons is still red from her humiliating encounter with one of her favorite celebrities.

On Sunday’s episode of The Real Housewives of New York City, the 55-year-old former creative director for J.Crew opened up about an embarrassing run-in she had with Ralph Fiennes — and how it still makes her cheeks hot just thinking about it.

During their girls trip to Anguilla, the ladies went around the dinner table and shared their most embarrassing moments. When it was Jenna’s turn, she recalled going to a “super expensive” restaurant on the Upper East Side” back when she’d “never seen a black card before.”

“At the entrance – it’s below – so you go down this very steep set of stairs,” she began. “As I'm walking down the stairs, my coat is dragging on the steps behind me and someone steps on it. I go head-first like a rocket!”

Jenna, who was dolled up in a chic silk dress, said she plunged down the stairs at “warp speed” (while telling the story, she even gestured to show how she bounced and slid with her hands).

“The sound I made,” she cringed as the ladies struggled to contain their laughter. “I slam into the wall and who picks me up? Ralph Fiennes!”

The fashion maven confessed the moment was all the more mortifying as she was "obsessed" Fiennes, whose 1996 movie The English Patient had just come out. (The performance caught a lot of eyes — it earned the actor the second of his two Oscar nominations after 1994's Schindler's List.)

“Literally my stockings are thrashed all the way down and I have rug burn all the way down my hands and legs,” Jenna continued of her run-in with Fiennes, now 60. “I’m, like, trying to stand up and just be cool and I want to cry so badly. It was, like, one of the most embarrassing moments of my entire life.”

In a confessional interview, she revealed that she ran into Fiennes again in a bar at a hotel in London “probably 10 years later.” Though the moment hasn’t left her mind to this day, she added, “I don’t know if he remembers, I don’t think so.”

Jenna wasn’t the only one who swallowed her pride and shared her most humiliating moment.

Jessel Taank told the group a story of how she ended up topless in a bar in Cancun during a spring break trip with her girlfriends.

“We're at the hottest club and inside this club is like a grotto, like there's like two levels,” she began while the ladies started giggling. “So I'm like, I want to go into the grotto. And I didn't bring anything — no swimsuit, nothing. And so I take off my dress and I'm wearing my underwear and I'm in the top level of this grotto and I see my other group of girlfriends like they're on the dance floor.”

She continued, “So I’m like leaning over and I'm like trying to get their attention, ‘Guys! Guys!’ I slipped in like f---ing headfirst into the second level of the grotto and my bra goes up like this and my face is in the water, by the way,” Jessel laughed, gesturing how her bra had gone over her chest. “So I'm basically topless in Cancun in the middle of the club and everyone is like ‘Yeah!!!’”

Brynn Whitfield also shared an embarrassing moment that involved a tampon and her first period.

“When I was, like, 12 or 13, I go to the bathroom and I got my period,” she recalled, noting how she started panicking and didn’t know what to do. “So I grabbed a tampon and I remember I go and lay on my little twin bed.”

Brynn confessed she had “never knew or explored myself” when she went “down there” to “find the hole.” She remembered then getting up from bed and going down the hall before she noticed that things “felt weird” as she walked around.

“I put the tampon in my butt,” she laughed as the group reacted in shock.

She explained how she wasn’t aware “there was another hole” as she grew up in a “Catholic, conservative” environment and had a lacking sexual education.
