The former Destiny's Child member and newlywed subtly made the announcement on Tuesday by posting a photo of Air Jordan sneakers with a small baby pair next to them on her social media accounts.
Rowland, 33, quoted a Lil Wayne song for the caption writing, "I'll be stuntin like my daddy….."
This will be the first child for Rowland with her husband Tim Witherspoon, who married last month in a private wedding ceremony in Guanacaste, Costa Rica.
Radar obtained exclusive photos of the couple's nuptials, which were attended by Beyonce and Solange Knowles just days after the singer's sister bizarrely attacked Jay Z in the elevator of The Standard hotel after the Met Ball.
Ironically, Rowland stated just one year ago that she wasn't ready for children because she's too selfish.
"I'm not ready, I'm not ready to have a child. I can be very honest. Because right now, I'm a bit selfish, a lot - I was gonna say a little - but I'm still selfish," she told E!
"I like my time, I like to wake up whenever I want to and I like to come and go as I please. I don't know if I'm ready to share that time with another person, I don't wanna mess them up."
A lot can change in one year!
