Sharon Stone flaunts bikini body and tell her fans to 'stay cool'

Sharon Stone just proved that age ain't nothing but a number!

The screen queen showed off her fit physique in a tiny black and white string bikini on her Instagram account on Monday. The 58-year-old star was all smiles in her swimwear and was exiting the pool. The scorching temperatures in California also prompted to her share the message, "It's so hot today! #summer16#staycool."

Stone is clearly enjoying summer. Earlier in July she kicked back on vacation with her kiddos and was spotted rocking out on a lake dock and cooking up a huge feast of spaghetti and red sauce for her family. She also showed off her outdoorsy skills on an ATV.

Stone isn't the only Hollywood star that's been beating the heat in skimpy swimwear this summer. Dozens of A-list stars have been spotted enjoying the summer months in lavish destinations like St. Tropez, Hawaii, Italy and the Bahamas. Check out all the hottest celebrity bikini bodies below:
