Jenna Lyons makes her runway debut — with support from ‘RHONY’ co-star Jessel Taank

From fashion executive to fashion model.

Former J.Crew president and current “RHONY” star Jenna Lyons took a turn on the catwalk for Lingua Franca‘s first-ever runway show Tuesday night, styled as a bellhop from the iconic Bowery Hotel.

Lyons walked her dog Popeye on a leash, wearing a top hat, bear-printed button-up shirt and jeans as well as a red overcoat and velvet moccasins — all part of the collection that was inspired by the downtown hotspot.

The 56-year-old “Housewives” was one of a gaggle of models who are close friends with Lingua Franca co-founder Rachelle J. Hruska MacPherson, including Molly Ringwald, Ivy Getty and Jill Kargman.

In the audience were even more celebs — including Lyons’ fiancée, Cass Bird, and her Bravo co-star Jessel Taank.

Taank even showed her support with her outfit, sporting a Lingua Franca cashmere sweater embroidered with the nickname she gave her friend: “Jenna F—king Lyons.”

Also in attendance were Katie Couric, Don Lemon, Susan Sarandon and Abigail Spencer.

The appearance comes one day after Lyons sat front row at the Marc Jacobs fashion show with two other co-stars, Sai de Silva and Ubah Hassan.

It was also the same night as the finale of the “RHONY” Season 15 reunion, which saw the fallout from Lyons defending Taank and her marriage against accusations from Brynn Whitfield.

Lyons also made waves at the reunion for her “dress,” which was actually a Balenciaga robe that she styled with a headwrap and De Beers diamonds.

“I just wanted to do something unexpected and playful,” she told the Daily Dish of the decision. “I can’t compete in the sexy dress category!”

She can certainly give the reality stars a run for their money in the model category now.
