Hot mama alert.
On Thursday, Serena Williams flaunted her athletic frame less than a month after giving birth to her first child.
The captionless shot featured Williams, 36, posing in front of a mirror in a one-piece, with her enviable closet in full view.
Williams and fiancé Alexis Ohanian, 34, welcomed daughter Alexis Olympia Ohanian Jr. on Sept. 1 in West Palm Beach, Fla., where she weighed in at 6 pounds, 14 ounces. The couple is set to wed later this year after getting engaged last December.
She is expected to return to the tennis circuit next year.
