Colson Smith has left fans stunned by his real age after he entered the Celebrity Big Brother house during Monday night’s launch episode.

The Coronation Street star, who is best known for playing Craig Tinker on the ITV soap, described being on the reality show as ‘madness’ as he revealed he was going to have to get over his social awkwardness to be on the show.

However the actor perhaps didn’t expect fans to be so blown away by his age, as viewers struggled to believe how young the star was.

The 25 year-old has been starring on Corrie for the last 13 years, possibly leading viewers to believe he was much older than in his mid twenties.

Taking to Twitter fans shared their disbelief, as one wrote: ‘He is not 25? This is that darts kid all over again’.

Another exclaimed: ‘Can you believe Colson Smith is only 25 years old? He looks at least 40’.

While another added: ‘It actually blows my mind that Colson Smith is ONLY 25’ and another wrote: ‘HES 25!!!! OMG’.

One viewer joked: ‘Colson being 25 will be the most shocking thing this series’.

Another couldn’t believe it as they commented: ‘COLSON SMITH IS ONLY 25???????’

Insiders have already predicted that Colson will go all the way as he is extremely ‘likeable and down to earth in real life’ just like his Corrie character.

A source told The Sun: ‘Big Brother producers have been in talks with Colson for months and it looks like a done deal.

‘They’re thrilled he’s keen to enter the nation’s most famous house because he’s a big name already loved by millions of viewers and they were hellbent of securing someone from Corrie as it’s great cross-promotion for ITV.

‘Colson’s character Craig is a huge favourite with soap fans and he’s just as likeable and down to earth in real life so don’t be surprised if he ends up winning the whole thing. He’s got all the ingredients of a Celeb BB champion.’

Colson joins Louis Walsh, Ekin-Su Culculogu, David Potts in the Big Brother house, as well as Sharon Osbourne, who has joined the show as their first ever house guest.

While it was originally reported that Sharon has joined the main CBB lineup, it’s since been revealed that she’ll be appearing on the show as a guest star.

It’s thought that ITV bosses were unable to match her fee demands, and so she will be entering the house as a late arrival, for just five days.

Sharon will be reunited with her X Factor co-star Louis Walsh in the house, and it’s hoped their hilarious antics will be a hit with viewers.

Music manager Sharon appeared on the first four series of The X Factor from 2004 to 2007, the 10th series in 2013, and the 13th and 14th series from 2016 to 2017, with Louis starring alongside her.

The pair became known for their bond and amusing interactions during auditions on The X Factor, with a reunion on Celebrity Big Brother being their first on screen in seven years.
