Kimberley Gail Marsh (previously Ryder, Lomas and Ratcliff;[1] born 13 June 1976) is an English actress, television presenter and singer.

In 2010, she finished in fourth place on Popstar to Operastar, a reality show featuring well-known pop stars being trained to sing opera.

[2] Her father was a joiner and in his spare time was the lead guitarist for the band Ricky and the Dominant Four who were a supporting act to The Beatles at The Cavern Club.

[4][5] Marsh provided session vocals for artists including Matt Darey, the group Freaky Realistic and the duo Hemstock & Jennings.

She sang in Norwegian on the latter's track "Arctic", which caught the attention of Paul van Dyk, and was remixed and re-recorded with additional vocals from Jan Johnston.

She was one of the five singers chosen for the newly formed band Hear'Say, along with Danny Foster, Myleene Klass, Suzanne Shaw and Noel Sullivan.

[10] Marsh made her television acting debut in 2005, in an episode of the BBC One soap opera Doctors, playing a character called Ruth Parry.

[11] In 2006, she played sex worker Kay Price in the first 2 episodes of Channel 4's soap opera Hollyoaks: In the City.

[12] Marsh joined the cast of Coronation Street, playing Michelle Connor from April 2006 a role she held until 2019.

[14][15] Becoming a regular character, her storylines have included a serious relationship with Steve McDonald (Simon Gregson), discovering that her son had been swapped at birth, the death of her eldest brother Paul (Sean Gallagher) and the murder of her other brother Liam (Rob James-Collier), her failed engagement to Ciaran McCarthy (Keith Duffy), surviving a minibus crash, becoming pregnant with Steve's baby, learning that Steve has also impregnated Leanne Battersby (Jane Danson), delivering a stillborn son Ruairi and being stalked by her ex-boyfriend Will (Leon Ockenden).

[16] The baby-swap storyline, which Michelle was central to, was largely panned by both fans and critics, columnist Grace Dent said of the plot; "...It feels like something ripped from a copy of Pick Me Up magazine and read to me laboriously over 22 weeks".

[18][19][20] Marsh, whose real-life son Archie was also stillborn, explained that it was important for her to take on the storyline in order to raise awareness of the issue.

[24] On 24 February 2019, it was announced that Marsh would be leaving the soap after 13 years and Michelle's final scenes were broadcast on 27 December 2019.

In February 2022, she was announced as one of the starring cast members of BBC's revival of their school drama Waterloo Road, which began airing in January 2023.
