Little Mix beauty Perrie Edwards has revealed that she often gets starstruck and once had a particularly embarrassing encounter with pop superstar Katy Perry.

During an interview with Entertainmentwise, the 'Wings' hitmaker explained that Perrie told her she was a fan of her style and the compliment caught her completely off guard. The 'Teenage Dream' singer told Edwards: "I love your hair. I've got photos of you on my laptop.”

Edwards then recalled her response, admitting: "I went 'I feel sick'. That's all I said. How embarrassing is that? I hope I get another opportunity to show my coolness.”

Member Jesy Nelson also revealed that she was shocked after Hollywood actress Jessica Alba joined a queue to have her photo taken with the Little Mix girls, adding:

"We were standing there having a picture and then Jessica Alba got in a little queue where people were taking pictures of us and got in the queue to take a picture of us. I was like 'excuse me you're Jessica Alba. I want a picture with you!'”
