Mel B's Scary Hot in Pink Bikini During Desert Vacation

Mel B's grabbing life by the horns pigtails ... and clearly living her best life right now.

Mel's out on vacay in Desert Hot Springs, CA where she was hanging poolside in a pink print bikini and pink heels. She's there with her hairdresser bestie, Gary Madatyan, who had a clear view of her fit bod.

Smart move to get some R&R before the heavy lifting starts. Remember, Mel claims the Spice Girls will perform at Prince Harry and Meghan Markle's wedding on May 19 -- and, of course, they have a reunion tour kicking off later this year.
