Tennis champ Serena Williams competed Saturday for the first time since the birth of her daughter at the Fed Cup in North Carolina. Her 5-month-old, Alexis Olympia Ohanian Jr., was decked out in red, white and blue. She was sitting in the stands with daddy, Reddit co-founder Alexis Ohanian, watching mom at work. Serena took to Instagram stories between sets, where she showed off video of her family right behind her. Serena reunited with her sister, Venus, Sunday to play a doubles match.
