Brooke Shields is one hot mama!
The 51-year-old former supermodel defied age when she hit the beach this week in a royal blue bikini and showcased her extremely fit physique. Shields was all smiles as she flashed her toned abs and posed her hand strategically on her hip.
She captioned the hot snap, "The hard work is starting to pay off."
She's likely referring to her taut tummy -- and whatever she is doing is definitely working. She polished off the rest of the her beachy look with a straw hat and jewelry.
Shields appears to be hanging out on vacation and later posted a photo with one of her good friends.
