The 33-year-old mom-to-be smiled over her shoulder as she cradled her growing belly. Rowland captioned the photo, "#P.R." as she is currently vacationing in Puerto Rico.

Rowland first announced her pregnancy on June 10 with a cryptic Instagram photo of baby sneakers. The Destiny's Child alum accidentally revealed that she's expecting a baby boy during an interview, in which she referred to her baby using the pronoun "his."

"Aw, f--k it! It's a boy. It's a boy!" she said after realizing her slip up.
