London: Model Alexa Chung will host a new fashion reality show "24-hour Catwalk".
The show will premiere on US television later this year, reports contactmusic.com.
The show is similar to supermodel Heidi Klum`s "Project Runway", with designers competing against each other in runway challenges.
Chung began her presenting career on Channel 4 breakfast show "T4" and also hosted fashion show "Frock Me" with designer Henry Holland.
She made her debut in the US with chat show "It`s On With Alexa Chung" in 2009 but the show was cancelled after just six months.
