The former 'Coronation Street' star - who played Marcus Dent on the ITV soap from 2007 to 2014 - admitted the "nicest" star he has met is 'Lord of the Rings' actor Viggo Mortensen, when he worked alongside in 2008 movie 'Good', but his comment about the unnamed unpleasant person has had the Twittersphere guessing as to who it could be.

Charlie wrote on Twitter: "Taking my cue from @BridgLondon, who’s the nicest celeb you’ve met? And who’s the nastiest?

Nicest - Viggo Mortensen was the absolute best when I worked with him.

Nastiest - someone I had to work with closely for a long time ..... (sic)"

Vicky Entwistle - who played Janice Battersby on 'Corrie' - sparked speculation that Charlie could've worked with the "nasty" person on the soap, as she replied: "I know!!!! X (sic)"

Former cobbles favourite Charlie didn't elaborate about who the unpleasant person could be.

He turned his attention to the "nicest" celeb, revealing Viggo bought him British newspapers, when he was working in Hungary, and gifted him sweets and cakes before he had even met the actor.

Charlie wrote: "My first day on set in Hungary, he went out and found a shop that sold British newspapers and put a load in my trailer, along with lots of sweets and cakes. That was before I’d even met him (sic)"

Former 'Footballers' Wives' and 'Holby City' star Laila Rouass admitted Hugh Jackman is among the nicest celebs she has met.

She tweeted: "Can I name someone else? @RealHughJackman was just the most beautiful man. I was flown to Sydney to audition for Wolfman and spent an afternoon with him and the director. Funny, warm, engaging...just everything you could want in a human being. Smiled for days afterwards (sic)"
