Victoria Beckham Reveals When She Knew It Was Time To Leave The Spice Girls

In a letter to her future self published in U.K. Vogue, Beckham shares it was an Elton John performance that changed her outlook on her career and ultimately, her life. "Remember years ago, watching your dear friend Elton John on stage in Las Vegas," the 46-year-old writes to herself. "He performed 'Tiny Dancer,' as if it were the first time, and you realised this was like oxygen for him. It was a life-changing moment — while singing and dancing was fun for you, it wasn't your passion. That day, you started your quest to uncover your own dreams. It was time to step away from being a Spice Girl."

Beckham went on to pen, "For the first time, you were venturing out on your own, and it was terrifying. It was scary to close a chapter that defined you."

It turns out the star is still reinventing herself — most recently she has been working toward the launch of a self-titled beauty line.
