"She's tall, she's blonde and she's beautiful. But back off, guys - she is also Martina's. Our amazing pictures are a clue to why Ms. Navratilova seemed less than distraught at being knocked out of Wimbledon without winning that record 20th title. After all, the pain of defeat in the mixed doubles is so much easier to bear when there's a kiss, a cuddle and an enjoyable singles match waiting at home. The 39-year-old tennis legend's latest love is stunning model Hunter Reno, who has even more going for her than those sensational looks. Her aunt is Janet Reno, the 6ft 2in pipe-smoking Attorney General of the United States, whose mother used to wrestle alligators, and who was so tough as a Florida cop she made Crockett and Tubbs from Miami Vice look like Miss Marple. The couple went to enormous lengths while they were here to keep their love a secret - coming and going separately from their rented house, Hunter cheering Martina on from the back of the stands instead of the front of the prestigious Players' Box. But the Sunday Mirror can tell their love story...As usual, Hunter had arrived back at the house, just a three minute stroll from the Wimbledon championship courts, some time after Martina. Twenty minutes later she went out again to go back and watch more tennis, but as she walked down the drive, Martina called her back. Smiling broadly, Hunter rushed into her arms and the pair fell into a tender embrace. Then Martina ran her fingers through Hunter's fair, short-cropped hair as they hugged and kissed. "They had love in their eyes," says our photographer, who snapped the happy scene by chance. "It looked like a spontaneous show of genuine affection. "When they parted, Hunter waved and blew a kiss before going back to the tennis." Martina and Hunter - who works for L'Oreal cosmetics and is a cover girl for upmarket magazines - have done well to keep their love under wraps for so long. Friends say they met more than a year ago at an Aids charity fundraiser. One said: "Martina met Hunter around the spring of last year and flipped. "Hunter dated guys until she met Martina, but they started going out and Martina persuaded her to join her at tournaments. They've been inseparable since. Hunter has had boyfriends, but since she met Martina, they're history. "I see them together regularly and there's no doubt they're in love." Hunter is thinking of selling her Manhattan penthouse and moving to Martina's home in exclusive Aspen, Colorado."
