Jenny Ryan, known as The Vixen on ITV quiz show The Chase, took to Twitter to tell fans about the incident.
Discussing the awkward run-in with EastEnders cast member Dean Gaffney, Jenny wrote: “I have just been evicted from my booked train seat in favour of Dean Gaffney. Oh, the indignity.”
However Jenny, 37, later revealed that Robbie Jackson star Dean had apologised.
Later she added: “Sometimes a Twitter whine works – Dean has sent his apologies and a cupcake. Ta, Dean!”
“I have just been evicted from my booked train seat in favour of Dean Gaffney”
Jenny also told fans that Dean had the “whole blommin’ carriage” as he was filming something.
However, she added that she was instead in a comfy seat just two carriages down.
Many of Jenny’s followers weren’t impressed though, judging by their replies.
One asked: “A cupcake? What about giving you your seat back?!”
While another told her: “You’re more important than Dean Gaffney.”
A third chimed in: “What a gent… NOT.”
However, one warned: “Don’t mess with Dean, I’ve heard he’s Wellard.”
The Chase airs weekdays on ITV at 5pm.
EastEnders returns to BBC One tonight at 8pm.
