Mel B, known in a past life as Scary Spice, is a judge on multiple reality shows these days, like America’s Got Talent and The X Factor. She also recently announced the Spice Girls will reunite to go on tour in 2019, which means she had better keep in tip-top shape.

Not a problem, if her home gym in her Hollywood Hills residence is any indication. You can see the cardio machines, treadmill and weights, but what you don’t see is the jaw-dropping pool Mel had just outside.
