Looking good, Carrie Underwood. The new mom, who gave birth to son Isaiah Michael about three months ago, took to Instagram on Monday to share a sneak peek photo of herself rehearsing for the upcoming CMT Awards—and the blond beauty’s post-baby bod is seriously on point. The 32-year-old country crooner captioned the pic, in which she’s rocking a tight white tee and a fitted black skirt teamed with a pair of flat sandals, “Rehearsals for the #CMTAwards I can’t wait!” The red carpet will also be Underwood’s first public appearance since giving birth, and it’s evident the gorgeous mama has working hard to get her body back.
