Nathan Sykes says he was left speechless after watching Fifth Harmony's Camila Cabello perform live at an awards ceremony.

The singer said he "melted" when he saw the group strut their stuff, with the Brit telling The Sun's Dan Wootton that he found the performance mesmerising.

He said: "I'm not going to lie, when I saw Fifth Harmony at the...was it the VMAs? I melted. And then I completely lost all ability to talk when I saw Camila. It was really embarrassing."

Tweeting a link to a video of himself revealing the crush, Sykes said: "I'm blushing haha thank you so much for having me in today! Good to see you!"
