In a YouTube video posted on Monday, the former tennis star documented the "baby shower-slash-gender reveal" party she hosted with her husband before their incoming arrival. Wearing a pink outfit, Serena said in the video, "I'm a little nervous because I don't have any contingency plan if it turns out to be a boy". Alexis first brought out a cake with yellow sponge inside that didn't reveal the baby's sex to "troll" his wife. "I'm doing this because I want to troll her and Olympia into thinking that this is the reveal of Jelly Bean.”
