Tennis champion and new mom Serena Williams has begun her winning streak again as she just nailed her first victory in the first round of the French Open. The 36-year-old was stylishly dressed in a black figure-hugging catsuit with a pink band around her waist, for the match that saw her play against Kristyna Pliskova resulting in a 7-6, 6-4 in an hour and 45 minutes.
