Weight Loss Journey! Katherine Heigl Shows Off Her Bikini Body After Welcoming Baby

Over a year after welcoming son Joshua Jr., Katherine Heigl is putting her post-baby body on display!

Along with a before-and-after collage, Katherine wrote, “It's been almost 14 months since Joshua Jr was born and it has taken me about that long to really get back in shape. The first pic was taken one month after he was born. The second pic was taken almost a full year later and the last pic was taken this weekend.”

“I wish I had a few from in between the first and second so you could really see how slow my progress was but alas…I was busy covering it all up those months, not posing in my unders!” the 39-year-old admitted.

Heigl, who just booked a new gig on “Suits” added, “Anyway, I have a beach vacation coming up, a new job I start filming in April and my deep desire to feel fit, strong and sexy propelling me forward the last two months to finally loose the last of my baby weight and do a deep dive search for the ab muscles I knew were buried under that belly somewhere!”

Katherine also revealed that she shed the weight with Kayla Itsines' Bikini Body Guide program. She revealed, “I won't lie, the workouts are real ass kickers but the progress I've made in only 5 short weeks has kept me motivated and inspired to keep going I am so grateful I've had a full year to find those ab muscles and get my butt back up where it belongs and wasn't forced by work to snap back into shape but it is time to make the strength, fitness and overall health of my body a priority and I am so grateful that @rachparcell shared her story and got this mama motivated!”
