The 37-year-old star is celebrating a double decade as Fiz Stape in the ITV soap, and she can still recall her "frightening but brilliant" cobbles debut.

She wrote on Twitter: "I can’t quite believe I’ve been pretending to be Fiz for 20 years @itvcorrie. I remember that frightening but brilliant first day like it was yesterday. It’s been joyous. I love those cobbles (sic)"

Jennie was inundated with congratulatory messages about the milestone from fans and stars of other soaps.

Hollyoaks' Annie Wallace - who plays Sally St. Claire in the Channel 4 show - tweeted: "I remember it well, luv... happy anniversary! x (sic)"

'Emmerdale' actor James Hooton - who has starred as Sam Dingle since 1995 - admitted he hopes Jennie remains in 'Corrie' for years to come.

He tweeted: "Congratulations on 20 not out! Long May it continue x (sic)"

Jennie recently admitted she felt as though she was acting out a play while portraying an epic 18-page 'Coronation Street' scene, as Fiz had showdown talks with her partner Tyrone Dobbs (Alan Halsall) about him growing closer to their lodger Alina Pop (Ruxandra Porojnicu).

She said: "All our scenes are usually three, four, five, six pages.

"It was 18 pages, half of the second half of a show.

"It felt like a little play that we did.

"We've had some lovely messages and people have said, 'Wow, that's the conversation I had with my now-ex husband.' "
