Little Mix have been gushing about Justin Bieber after a surprise meeting with him last weekend.

The Little Mix girls – Perrie Edwards, Jesy Nelson, Leigh-Anne Pinnock and Jade Thirlwall – bumped into the ‘What Do You Mean?’ star when they were all in attendance at the BBC Radio 1 Teen Awards.

Talking about the chance encounter, Jade told the Daily Mirror: “We loved meeting Justin. We're all such huge fans. It was a big surprise when he knocked on the door to say hello.”

She went on: “He's had such big success all over the world, and such a massive artist - so it meant a lot to us him wishing us luck and giving us good vibes for our performance.”

Little Mix are on track to score their first ever No. 1 UK album later this week as ‘Get Weird’ is at the top of the mid-week chart update.
