Little Mix "chin-wagged about boys" with Taylor Swift.
The girl group, formed of Perrie Edwards, Jesy Nelson, Leigh-Anne Pinnock and Jade Thirlwall, joined Taylor on stage for one night only during her 1989 tour in August.
The band and Taylor performed Little Mix's recent hit Black Magic, but also found time to enjoy some girl time backstage.
"She's like a model! She's like a Victoria's Secret model, she's gorgeous!" Perrie told British radio station Capital FM . "But we just had fun with her, so she's lovely to be around, she's such a nice girl.
"We just chin-wagged about boys, she's very humble and down to earth!" Jade added.
And Leigh-Anne was mostly struck by Taylor's "business sense". She admitted the girls were incredibly inspired by the multi-millionairess.
"She's just very inspiring, just being with her, being on stage with her, we learned a lot. She's incredible," Leigh-Anne said.
Taylor has collaborated with a host of musical stars during her career. But Little Mix aren't sure whether the time is right for them to ask for a duet.
"We felt it was a bit too soon to ask," Jesy said.
The girls previously revealed they were stunned by just how genuine Taylor was. When Perrie forgot her shoes for the performance, Taylor rushed to her aid and offered a pair of her own heels.
"I had no shoes," Perrie told MTV. "We thought, 'Oh we would rock up in heels.' Little did I realise I'm like Bambi on ice when I wear heels so I was like 'Oh I need some shoes and she was like, 'Wait a minute,' she went to her wardrobe, brought back a basket full of boots, heels, shoes, everything and was like, 'Is this OK?' And I was thinking, she is so nice. She didn't have to do that. She's just so genuine.
"You don't realise until you meet her and you're like holy crap how does she stay so on top and so nice and so genuine? She's really, really lovely."
Taylor has enjoyed some stellar guest appearances during her 1989 tour, with the most recent coming from Rolling Stones legend Mick Jagger as she hit Nashville this weekend (26-27Sep15).
