Reader Nishanth Gopinathan sent us this picture from New York.
'We recently met Martina Navratilova who was on a promotional visit to Manhattan, the week before the US Open started, to push her book Shape Your Self,' writes Nishanth.
'My son Nidhin was pleasantly surprised when after autographing the book, she called him back, high-fived him, and asked me to take a picture of them together.'
So rush those photographs to us!
