Beloved Rita Sullivan actress Barbara Knox has opened up about her long run on the ITV soap opera Coronation Street as she turns 90.

This comes as the star commemorates her time on the cobbles in a special tribute show hosted by The Chase presenter Bradley Walsh.

However, despite becoming a fixture on the programme, there have been times when she was left "terrified" while acting on the show such as near the start of her career.

Corrie legend Barbara Knox reveals time she was left 'shaking' and 'terrified' on show

Joined alongside some of her Coronation Street co-stars, Barbara Knox revisits some of her most iconic moments as well as some of her shakiest.

One such time was in 1972 when she first landed a full-time role on the ITV soap opera, revealing that she nearly messed it all up.

The Corrie star recalled: “I was so terrified.

“Bill Roache was there as Ken Barlow and he’s stood there saying whatever he’s saying and I’m shaking.

“I lost my voice. Nerves.

“But Pat Phoenix (Elsie Tanner) was marvellous.

“She said, ‘It’s just nerves, you’ll be fine tomorrow when we’re in the studio’ — and I was.

“It was so magical and they were wonderful to me, made me very welcome and looked after me.

“I was very fortunate — I only had a short contract, three or four more episodes, but thank God somebody said after all that, ‘We’ll keep her in it’.”

Bill Roache, 91, however, revealed that he had no idea why she was so nervous, even all these years later.

He said: “If she was nervous, you wouldn’t have known it. She looked so relaxed.

“Impeccable comes to mind.”

Barbara Knox At 90 airs on ITV at 9pm on Friday, October 13.
