The 45-year-old singer, whose real name is Melanie Chisholm, shared on Jay Rayner’s Out to Lunch podcast this week that Beckham is just "petrified" of performing.
"I'm sure, Victoria wouldn’t mind me saying, the Olympics was hard for her," Mel C said, referring to Beckham's last performance during the London closing ceremony in 2012. "You know, she's moved on, her life has changed, and she just doesn't have that love of performing, and in fact, it completely petrifies her."
Mel C, Geri Horner, Emma Bunton and Mel B announced in November that they'd be hitting the road for a string of shows in the U.K. later this year, sans Beckham. In a January interview with The Guardian, Beckham said that when she sees her former bandmates on stage, she's sure she'll feel a bit "left out," but said that her fashion empire is now her main focus.
"She's extremely busy and successful in what she's doing. She has put her heart and soul into her business, and … to step away from that, and … not give it the time that she does at the moment would be difficult," Mel C told Rayner. "But also, I'm sure, if she felt passionate about being on stage and loved it, then she'd be there."
"We're all very sensitive of that, and we completely understand," she continued, insisting that she and the other women harbor no ill will towards Beckham. "We're all sad that Victoria won’t be joining us, but it's all genuinely very supportive you know, obviously understand and support her."
