Ozzy Osbourne's 23-year-old daughter replaced actress and model Liz Hurley on the show, who has been the face of the last two series.

Project Catwalk sees aspiring fashion designers compete for success and is based on a US format presented by supermodel Heidi Klum.

Featuring London-based fashion designer Ben de Lisi as mentor, it was first broadcast in the UK two years ago.

The most recent, third series was watched by around 110,000 viewers, compared to around 300,000 for the previous instalment.

A Sky One spokesman confirmed the show would not return and that the broadcaster was looking for "female-friendly" replacements.

He said: "Project Catwalk was a great addition to Sky One's schedule. Kelly Osbourne, Ben de Lisi and the team have provided a fantastic platform for genuine talent, introducing the rising stars of fashion to the UK.

"We felt the series had come to a natural end and we're now looking for some new female-skewed formats for the 8pm slot to complement our success in the 9pm and 10pm hours."

Osbourne, currently dating model Luke Worrall, has been in popular demand since being introduced to British audiences on her family's MTV reality show The Osbournes.

She recently performed on the West End stage in the musical Chicago and hosts a Sunday evening slot on Radio 1, tackling relationship, health and education issues.
