The mother of two wore a form-fitting silver sequined dress with matching heels, and was pictured with her hands over her stomach, cradling what appeared to be a baby bump.
Berry didn't attempt to hide her pregnant-looking stomach as she posed for photos.
If she is expecting, this would be the first time the actress has given birth later in life. Berry had her last child, three-year-old son Maceo, at the age of 47. She's also mom to Nahla, 9, who she shares with her ex Gabriel Aubry.
Who the potential baby daddy could be remains a mystery, as the actress is not publicly with anyone at the moment. She divorced her French actor husband Olivier Martinez in December 2016, with whom she had Maceo.
"I didn't think it was possible to have another baby," Berry told Ellen Degeneres in 2014 when she was pregnant with her second. "So, I've learned never to say never." Do you think Halle should have another kid? Sound off in the comments!
