Outhwaite left EastEnders in 2002, shortly after the departure from the soap of co-star Martin Kemp, who had played her husband.

In 2002, she was given a leading role in BBC army drama Red Cap, however the series ended in 2004. During Red Cap, she starred with Nigel Harman who later joined EastEnders himself. According to press reports, she also dated him for a short time.

She fronted an advertising campaign as part of a one million pound contract with cosmetics company Avon; she also modelled the Spirit range at Debenhams in 2004.

She had been edging into the Hollywood film industry, starring alongside Wesley Snipes in 7 Seconds. However this had very little success.
