Flawless! Kelly Rowland seems to be loving her first pregnancy. The mommy-to-be, 33, has been updating her fans with photos of her growing baby bump on Instagram, and on Saturday, Aug. 9, she shared one of her most stunning looks yet. 

In a black, form-fitted dress, the Destiny's Child alum looked over her shoulder while cradling her growing belly. She simply captioned the pic, "#P.R."

Rowland is currently vacationing in Puerto Rico at the St. Regis Bahia Beach Resort, which provided the elegant backdrop for her glowing photo. 

In late July the "Kisses Down Low" singer accidentally revealed she's having a baby boy during an interview with FOX411 in which she continuously referred to her baby using the pronoun "his." 

"Aw, f--k it! It's a boy. It's a boy!" she declared after the slip.
