Sept. 29 (UPI) -- New mom Serena Williams was missing her daughter as she stepped out this week.
The 36-year-old tennis pro shared a post-baby selfie Thursday on Instagram ahead of her first outing with fiancé Alexis Ohanian since welcoming daughter Olympia.
The mirror photo shows Williams striking a pose in her extensive walk-in closet. The six-time U.S. Open winner showed off her figure in a black t-shirt and matching short-shorts.
Williams and Ohanian, the 34-year-old co-founder of Reddit, later documented their day without Olympia on Snapchat.
"First day out. We miss her already," the tennis pro captioned one video. She confessed "We miss Olympia" in another clip while using a watermelon filter with Ohanian.
Williams gave birth to Olympia on Sept. 1. She said her daughter shares her "powerful" body type while thanking her mom in an open letter on Reddit last week for her support amid body shaming throughout her career.
"I was looking at my daughter [OMG, yes, I have a daughter] and she has my arms and legs! My exact same strong, muscular, powerful, sensational arms and body," the tennis pro wrote. "I don't know how I would react if she has to go through what I've gone through since I was a 15 year old and even to this day."
"I've been called man because I appeared outwardly strong," she said. "But mom, I'm not sure how you did not go off on every single reporter, person, announcer and quite frankly, hater, who was too ignorant to understand the power of a black woman."
