Hi, Kian here,

This week we've been living it up in mad, crazy Las Vegas - the city that never sleeps.

We've been here shooting new footage for our forthcoming Rat Pack album, which will feature songs by legendary singers like Frank Sinatra.

Las Vegas is an amazing place. It's known as Neon City and at night it's like being on a movie set. The hotels are all themed, so you've got New York, Paris and there's even a hotel, The Venetian, which has a canal and gondolas on the SECOND FLOOR.

As I walked past a hotel the other night a volcano erupted and it was so real I nearly jumped out of my skin.

Then there are the gambling casinos where people chance their luck all day and all of the night. I saw a bride and groom coming in straight from the little chapel to try their luck on the gaming machines and tables.

It was in Las Vegas that Sinatra, Dean Martin and Sammy Davis Jnr staged their legendary shows, so we're trying to capture the atmosphere there for our own album.

I've heard from my family back home that there were pictures of us living it up on a beach in Los Angeles in the trip out. We had a ball and soaked up the sun before heading off to work in Vegas. It's a tough life. Honestly!
