Throughout the 1970s and 1980s, Gee had guest roles in many television shows, including Return of the Saint, The Glittering Prizes, Hammer House of Horror, The Professionals, and Alas Smith & Jones.
In 1981, she starred as Miss Griffin in Nigel Kneale's short-lived LWT sci-fi comedy series Kinvig, alongside Tony Haygarth.
In 1985, she appeared as Penelope Keith's disruptive actress sister in the ITV sitcom Moving, and the following year co-starred with Pat Phoenix in Constant Hot Water.
Gee's last television role was as Doreen Heavey in Coronation Street, the mother of Maxine Peacock and a part she played in regular intervals from 1999 to 2004.
The character of Doreen was scatty and flirty, and during her time on the show, had a brief flirtation with Mike Baldwin, a feud with Vera Duckworth, and was a constant source of irritation for her son-in-law Ashley Peacock, when she arrived at his and Maxine's house following a split with her husband Derek, whom she was reconciled with in 2003.

The same month, in her capacity as a counsellor, Gee was interviewed on Jo Good's BBC London 94.9 radio show, talking about addiction.
Gee married the actor and director Ken Campbell in 1978, with whom she had a daughter, Daisy; the couple divorced after five years but remained on good terms.
