Serena Williams may be pregnant with her first child.

The tennis star appeared to announce the big news on Snapchat with a photograph of herself in a swimsuit while showing off what many believed to be a growing baby bump.

Williams accompanied the photo with the caption “20 weeks,” which caused many to believe she was referring to how far along she is in the alleged pregnancy. She later deleted the photo.

Williams, 35, is engaged to marry Reddit co-founder Alexis Ohanian. The pair announced their engagement back in December.
