Snowdon was born in Welwyn Garden City to insurance salesman Nigel and hairdresser Lydia Snawdon.

[3] She gained a scholarship to the Italia Conti Academy of Theatre Arts, where her classmates included Naomi Campbell.

[citation needed] After gaining too much additional height, and after her parents split up when she was 17, Snowdon stayed in London and worked briefly as a dance and yoga teacher.

[4] Spotted by a Premier Model Management agent at age 19 while dancing at a rave at London's MFI club,[5] she was auditioned and signed up.

[citation needed] Her modelling career led to appearances in Maxim, Arena, Loaded and GQ.

[citation needed] Snowdon's first presenting role was in 2003 on BBC3's Fightbox - a children's show in which contestants created 'avatars' to battle each other.

At the end of August 2008, it was announced that Snowdon was to be the permanent replacement for Denise van Outen on Capital London as co-host with Jonny Vaughan.

[15] Snowdon was given the nickname 'Eggy' on the show by colleague Dave Berry after her penchant for boiled eggs and the smell they gave off in the studio.

[19] In November 2010, after turning on the Bond Street Christmas Lights, Snowdon was rushed to hospital and diagnosed with viral meningitis.
