Gwyneth Paltrow can't believe that her daughter Apple Martin is already 17 years old. The Goop founder, 48, posted a photo of her grown-up, lookalike daughter sitting by the ocean sporting beachy waves and hot pink nail polish on Instagram along with a heartfelt message for Apple's 17th birthday on May 14. "Can it be? 17 today?? My sweetest girl... YOU ARE MY LIFE! You make me belly laugh every day. You are brilliant and hardworking. You are fully YOU which I respect and admire so much," Paltrow wrote.
