Leigh-Anne Pinnock "couldn't speak" when she met Rihanna.
The Little Mix singer admits she was overwhelmed when she came face to face with the 'We Found Love' singer whilst attending the BRITs with her bandmates - Jesy Nelson, Perrie Edwards and Jade Thirlwall.
Perrie admitted she "had never been such a mess" as when she met Hollywood star Kate Hudson, before Leigh-Anne added: "For me it was Rihanna. I couldn't speak."
Bandmate Jesy agreed: "Oh when she said 'I like your hair' and you couldn't even speak!"
Perrie said: "I don't think we'll ever be cool will we and not freak out when we meet people we love!"
And when they do go to glitzy showbiz events, the girl group are like "four fan girls".
Speaking on their new talent show, Jade admitted: "We usually stick to ourselves, eating the free bread."
Perrie added: "We're like four fan girls sat there at the BRITS, like we won tickets to be there."
Meanwhile, Jade previously slammed the "weird stigma" surrounding girl bands.
She shared: "I think for women in general, it’s hard getting the recognition you deserve. And so for a group of women, or a girl band, it's incredibly hard. Because I feel like, for some reason, there’s this weird stigma attached to being in a girl group, especially a pop band.
"It took us literally years to prove to everyone that we're credible, that we write our music and we actually stand up for things that we believe in. It did take us a long time to get to that point. Even with the Brit Awards, it's incredibly hard to even be nominated for the group category - I don't think a girl group has ever won Best Group at the Brit Awards which, for me, is mindblowing. So I think there’s still a long way to go in terms of celebrating women. Properly. And appreciating what we’re about."
