Cue the gasp, then giggles.

Rebecca — mercifully — saw the funny side. “His ex-girlfriend’s name is Sarah, [and] so is one of my middle names,” she explained to Newsweek. 

“I understood he was nervous and slipped up.”

“I’m a lot more outgoing and sociable,” Rebecca continued. “Andi [short for Andrew] is more introverted and sensible.”

Still, the blunder was undeniable. “He didn’t even realize he’d left ‘Rebecca’ out,” she recalled. “I told him and he said, ‘I’m so sorry, I was so nervous that I’d do something wrong.’ We laughed about it.”

Rebecca’s TikTok post (@scalesfeathersandfur), cheekily captioned “Oh dear,” has racked up more than 30,000 views — and a comment section split between sympathy and scorched-earth.

“To be fair I think he just got HER names in the wrong order due to anxiety. He looks besotted with her. Congratulations,” one viewer wrote.

“Ross and Rachael … I mean Emily moment,” joked one commenter, referencing the infamous “Ross says Rachel” moment from “Friends.”

Others weren’t buying it: “Oh no, that’s awful. I would have been so upset.”

One user dubbed it “instant romance cancellation.” Another chalked it up to wedding‑day jitters: “things like this happen when you are nervous…”

One simply called it a “no-go.”

Looks like she took “Sarah” out of the vows — but not out of her happily‑ever‑after.

And she’s hardly the first Brit bride to see her big day go off‑script. 

As The Post previously reported, one Yorkshire father of the bride accidentally marched halfway down the aisle without his daughter, while another groom was left “humiliated” after a prank garter toss swapped his bride for a groomsman. 

Ultimately, whether it’s name‑drops, aisle‑walk mix‑ups or under‑the‑dress dupes, wedding‑day blunders have a way of living rent‑free in everyone’s memories — and on the internet — for years.
