Sam Smith thinks Kim Kardashian West's outfit at the BRIT Awards with MasterCard was the "best thing".

He told BANG Showbiz: "I think Kim Kardashian's outfit was the best thing I've seen in my life."

In her usual risque style, Kim donned a cut-out black top, which nearly revealed all to the 15,000-strong crowd and the millions tuning in at home.

Meanwhile, Sam - who was also honoured with British Breakthrough Act - admitted he was stunned by his international success but thoroughly enjoys travelling around the world as part of his job despite being jet lagged most of the time.

He said: "Genuinely, from my heart, when I brought out this record I thought it was only going to travel so far.

"The fact that I was in Tokyo five days ago, the fact that I'm getting to travel and see the world is so amazing and so important, and the fact that I got recognition for that is amazing because I've been very jet lagged a lot."

Sam - who received the Critics' Choice Award at last year's ceremony - felt like the whole thing was "déjà vu" this year and was full of praise for his rival, Ed Sheeran, who also picked up two gongs.

He shared: "This is déjà vu, I was here last year. This is amazing and [the trophies] are so beautiful.

"I'm so happy that Ed Sheeran won those awards, I truly think he deserves them."

When asked what he wanted to say to his loyal supporters, he said: "To my fans, I love you so much, more than you will ever know.

"I can't wait to get my second album to you!"
