One user said: "I refuse to believe that Mel C is 50 today. In my head she's still doing backflips in tracksuits & if she was 50 that would mean I'd be turning 40 in 5 years!"
Another added: "Mel C is 50 today I’m honestly shocked."
A third gushed: "Would u believe if I say that you look and sound better at 50 than in your 20s?!"

Mel found fame in the girl group, the Spice Girls, in 1994.
The band's debut single Wannabe reached No1 in 37 countries in 1996.
Their first six singles went to No1 and they became a symbol of ’90s feminism.
Geri quit in 1998 and the band took a hiatus in 2000, with all five girls enjoying successful solo careers.
In 2007 they briefly reunited for a worldwide tour with tickets for their London O2 gig selling out in two minutes.
Five years later they performed at the London Olympics closing ceremony.
And while there is no news of a reunion just yet, Mel has said: “As we get older, the Spice Girls are learning the need to give each other space.
“In the ‘90s, we would go 24/7. We were young, we were ambitious, we were under a lot of pressure, we were knackered and there were flare-ups.
“All bands have similar stories, but as time has gone on, we just have that real respect and appreciation for each other.

“Because we know without each other, we never would have achieved what we did and we wouldn’t have the lives and careers that we have now, so it’s quite beautiful."
She added: “I love it when bands get back together after a break of five or 10 years because you know they probably appreciate it more than ever.”
