Serena, 37, may have not won the U.S Open this year, but she certainly won over the red carpet!
The tennis star stunned in a simple white silk dress that she paired with yellow leather, pointed heels. She accessorized with a dainty necklace and a few necklaces and rings while she kept her light-brown locks down in tight curls.
Alexis, 36, who is the co-founder and executive chairman of Reddit, looked dapper in a navy blue suit that he paired with a light-blue button down shirt. He gave his outfit a casual vibe by finishing off in shiny black sneakers.
The couple, who shares 2-year-old daughter Olympia, stepped out in support of The Game Changers, which is a documentary about helping people eat and live properly by showing elite athletes, special ops soldiers, and visionary scientists explain the truth about meat, protein, and strength.
The executive producers include Titanic's James Cameron and Pamela Anderson. Arnold Schwarzenegger, professional race car driver Lewis Hamilton, actor Jackie Chan, tennis star Novak Djokovic and NBA player Chris Paul were also involved in the making of the movie.
After the premiere Serena was seen leaving Paradise night club in Times Square after partying the night away! She was all smiles as she posed with a few fans before getting in her car.
Just 48 hours before, Serena was fighting for her 24th Grand Slam title and fell short to 19-year-old Bianca Andreescu.
Bianca ended up beating the veteran in two straight sets, making her the fifth best women's tennis player in the world. Serena currently ranks as the ninth best player.
