Why Melanie C Is So Proud of 'Brave' Friend Billie Eilish (Exclusive)

Spice Girls singer Melanie C is opening up about how proud she is of pal Billie Eilish, describing the young chart-topper as “wise beyond her years.” Eilish previously shared how Melanie C’s encouragement to be more present during her whirlwind rise to fame were the greatest words of wisdom she had received.

While talking with ET’s Deidre Behar to promote her new single, ‘Blame It on Me,’ Melanie C shared how the two developed a friendship, which “came from nowhere.”

“It's very odd,” she says. “I am such a huge fan of her, her music, her brother and her family. They're the most wonderful people. And, I went along to see her show in London towards the end of last year -- she was playing quite a small theater in London. It was 2,000 people and she'd already outgrown it. She's such a huge star, but it was one of those moments when you think, ‘Wow, being in this audience is such a privilege,’ because you're never going to see her in this environment again.'”

“The room was full predominately of teenage girls, screaming and singing every word, every ad lib, and I just felt this really mad connection because it took me back to being a Spice Girl,” she adds. “It's quite weird because traditionally you have women or girls screaming for boys, whether it's boy bands or male artists -- when you think about Beatlemania or One Direction. So, it just really resonated with me.”

Melanie C said she was able to meet the family at the gig, recalling how Eilish’s dad in particular is a big Spice Girls fan, which prompted plenty of jibes from his loved ones during the introduction. The 46-year-old singer had little idea how impactful her advice to Eilish, 18, would become, but is pleased her words “struck a chord” with the musician, who has blown up globally in the past year.

The “Who I Am” singer also praised Eilish for how she has been using her platform for good, such as urging fans to be body positive, and speaking out about racial injustice amid the Black Lives Matter movement.

“She's so wise beyond her years,” Melanie C says. “She knows she has a very powerful platform to be speaking from and she's using it in the best way. And, it's brave because everybody has an opinion and everybody is ready to criticize when you're in those positions. I feel extremely proud of her.”
