The emerald green floor-length dress from Versace pronounced her baby bump well enough.
The American tennis champion, Serena Williams who had already announced her pregnancy at 20 weeks, walked into the venue of the prestigious event with her fiance Alexis Ohanian, who is co founder Reddit.
Serena was all smiles as she posed for photos, showing off her growing baby bump.
Serena, 35 and Alexis, 33, were engaged in December 2016. He proposed with a large diamond ring, which she showed off in January.
They had been dating since 2015 but have mostly kept their romance out of the spotlight, though Serena does post pictures of them on her Instagram account from time to time.
