The 'Coronation Street' cast cannot resist referring to Sam Aston as "Chesney" in real life.
Sam Aston
The 25-year-old star has played Chesney Brown on the ITV soap since 2003, and Kym Marsh says she and her 'Corrie' co-stars often call him by his character's name off-set, and that was no different when some of the lads were planning pranks ahead of his recent stag do.
She said: "Sam Aston - or Chesney as we all call him on and off set - looked like he had a raucous time on his stag do in Edinburgh with his pals, including Corrie's Alan Halsall, Andrew Whyment and Colson Smith.
"I overheard the boys at work saying they were going to play some tricks on him, so I'm sure they had a wild time."
Sam joined the soap when he was just eight years old - and Kym still thinks of him as a fresh-faced youngster.
Writing in her OK! magazine column, she added: "I still can't believe he's getting married, I still think of him as eight years old."
Sam certainly seemed to enjoy his Edinburgh stag do - ahead of his wedding to fiancée Briony Gardner.
He was made to don a ginger wig and kilt for a night out with his stags, which Alan seemed to enjoy.
The 36-year-old star shared a picture of himself and Sam, who was dressed in tartan, and he added the caption: "McChesney"
Alan also shared a snap of himself, Sam, Andrew and Colson all lying in a ball pit, and the quartet were all smiles.
