Alexa Chung threw on a sparkly dress and headed to Jimmy Fallon's talk show to chat up her new TV show, 24 Hour Catwalk. The British television presenter joked with Fallon about her previous TV gig as host of It's On With Alexa Chung.

"Sorry about last time: I'm back in America again - it's all happening. It's off with Alexa Chung, It's on with Alexa Chung, and now we're back!"

As for her new reality show, which debuts in the US next week, Alexa laughed that the show was "incredibly mean." Why? Perhaps it has something to do with the fact that it involves four designers competing against one another to create a fashion collection in just 24 hours. Yikes!

The newly single Chung, who recently broke up with Arctic Monkeys singer Alex Turner, also revealed she spent Christmas back in Hampshire, at a "pub with no name" drinking moonshine. That's our gal!
