Alex Rodriguez may still be feeling the heat from the MLB, but he was showing no signs of stress as he was surrounded by women including tennis icon Martina Navratilova at Larry Gagosian’s Art Basel bash at Mr. Chow in Miami Beach on Tuesday night. The Yankee slugger and girlfriend Torrie Wilson were spotted in a booth with Navratilova and her girlfriend Julia Lemigova. A source said, “Alex was having a great time, surrounded by at least eight women. Martina’s girlfriend was sitting on her lap, and they looked really happy.” The spy added, “At one point, a group of guys challenged Martina to a doubles match at Flamingo Park the following morning. She was a good sport and joked about going.” Also at the bash were Sean “Diddy” Combs, Cindy Crawford and Rande Gerber and top art collectors and dealers.
