The 'Mamma Mia: Here We Go Again' star was at work on the day she was off to see the girl group and admitted she was "livid" when filming overran and she feared she would miss seeing the 'Wannabe' hitmakers perform.

She confessed: "The night of going to the Spice Girls gig they kept me later than they should have. They went overtime and I have never thrown a tantrum on set before, and I was livid. I thought I was going to miss the Spice Girls!"

And Lily admits she had one of the "greatest days of her life" at the concert and got to go backstage to meet the foursome - Emma Bunton, Geri Horner, Mel B and Mel C - and her and her friends even filmed a video with Emma.

Speaking to Mark Wright on his Heart radio show, she added of her time with the Spice Girls: "I love Emma Bunton so much. She met me back stage and it was one of the greatest days of my life. I was with my two best friends and my other best friend lives in New York and Emma did a video with us and was like 'Hi Danni' and honestly us four best friends have known each other since we were eleven, it was one of the greatest moments of our life. I adore her."

Lily "started crying" when she spilled the details about the day when she was back on set.

Her co-star Armie Hammer revealed: "Lily came to work the next day after the Spice Girls concert and while in the makeup trailer talking to her makeup artist about the fact that she got a video with Emma, she started crying."
