Katy Armstrong is a fictional character from the British ITV soap opera Coronation Street, played by Georgia May Foote.

Katy was killed in an off-screen car accident in Portugal on 18 October 2017, facilitating the return of Joseph (now William Flanagan).

When Chesney is kidnapped by John Stape (portrayed by Graeme Hawley), she believes he has disappeared and decides on an abortion, but changes her mind when he returns.

A fertility clinic counselor questions whether Katy is emotionally strong enough to give up a baby, causing Izzy to change her mind about surrogacy.

Katy discovers that Gary tried to kiss her surrogate mother, Tina McIntyre (Michelle Keegan), and inadvertently reveals the truth to Izzy.

Katy and Gail hear the way that Dev and Kal are talking about them, and they come to a decision where they will work part-time, with the wages being pushed up by £1.

When Katy finds out that Anna slept with Owen's former business partner, Pat Phelan (portrayed by Connor McIntyre), she decides to take Joseph to live in Steph's flat.

On 9 June 2010, Daniel Kilkelly from Digital Spy announced that former Grange Hill actress Georgia May Foote had joined the cast of Coronation Street as Katy Armstrong.

[2] Foote's "feisty and outspoken" character was introduced as the sister of Izzy Armstrong (Cherylee Houston) and a love interest for Chesney Brown (Sam Aston).

[3] A show spokesperson explained "She loves the fact that he flogs stuff down the market, and he can't believe his luck when she asks him out.

"[4] The actress commented that she enjoyed working with Aston, as they had attended the same drama school and had "a laugh" together, a fact the writers reflected on screen.

[5] However, shortly after Chesney arrives at Katy's, Owen decides to stay home and "scuppers the young lovers' plans".

[6] Kilkelly reported "However, after Katy continues to push the idea, Chesney is expected to change his mind and begin looking for a flat that he can rent with his girlfriend.

Heras commented that his character has not really noticed Katy before, as she is a stay-at-home mother, but seeing her "dolled up" and in his environment catches his attention.

[9] Foote believed that Katy had not had a "teenage wild time" because of her relationship with Chesney and their son, so her head is turned by Ryan and it is exciting for her.

[8] Chesney later proposes to Katy in front of their family and friends at Faye's (Ellie Leach) birthday party, but hours later he learns about her affair with Ryan.

[11] Executive producer Stuart Blackburn confirmed that Katy would not be killed off and that the door would be left open for a possible return in the future.

[14] Roz Laws, writing for the Sunday Mercury, commented "Katy and Chesney are barely out of nappies but the young lovers are moving in together.

"[15] During her review of Coronation Street's Christmas storylines, Sarah Dempster from The Guardian commented "Sing hosanna, then, for Katy Armstrong's uterus.

The impetuous organ presented Weatherfield with its first ever nativity-within-a-nativity, a neonatal turducken that would (temporarily) muffle the chaos and (briefly) drown out the boo-hooing.

"[16] In February 2013, Laura Morgan from All About Soap wrote "Forget the upcoming Rovers fire, the most smoking thing on the street has to be the growing attraction between hot couple Katy and Ryan.
