Alexa Chung admits her new fashion TV show is "really intense." The British beauty - who creates her own fashion range as well as TV presenting and DJ-ing - admits "24 Hour Catwalk," where designers are challenged to create a runway collection in a day, is tough and she believes even she began to go crazy as she had to stay up as long as the contestants.

"It's a very mean show. It's really intense. There's designers - there's a first round challenge where two of them go, and then the next two are really excited and pumped to be through and then we're like, 'Wait, you have to create a collection in 24 hours'. So then they have to stay awake all through the night. It's very mean, they get very emotional. But it also involves me staying up for 24 hours too! By episode six I was losing my mind," she said when speaking about the show on Late Night with Jimmy Fallon.

Alexa is loved by many designers, with Christopher Kane previously stating she manages to always look phenomenal: "It was just one of those things. She contacts me, she wanted to wear something so it's great. She looks phenomenal, she always does."
