The snap back is real inside the Kardashian West household.

Kim Kardashian West just gave birth to her adorable son Saint in December, but the reality show star—who said she reached 205 lbs. with baby No.2— has already lost over 60 lbs. She shared the news on Snapchat April 27, with an image of her scale at 139 LBS. The caption read: "You guys!!!! Pre baby weight was 135!!!!"

Well, the "Keeping Up With the Kardashians" star is celebrating her success by showing some skin while out and about with husband Kanye West in New York City on Sunday, May 1. Kim, 35, looked stylish in a short denim skirt, a fitted, sleeveless top and a long duster coat. She paired the look with matching electric blue Gianvito Rossi heels.

Rapper Kanye wasn't far behind as the two headed out to fittings for the upcoming Met Gala in New York City. The "Selfish" author hasn't confirmed which designer she's wearing this year, but said she was excited for fans to see what she has in store.

Back in January, Kim set her fitness goals and shared them with the world. "I gained 60lbs during my pregnancy but have been an extra 10 lbs up for the last few years so it's time to really get to my goal," she wrote on social media back in January. "This is going to be soooo f------ hard but I can do it and I can't wait to share it all with you!#BeastMode #WhosWithMe ?!?!?!"

After she successfully lost weight with Atkins in 2013 following North's birth, Kim returned to the diet this year. She's reportedly using the Atkins 40 program, which allows more carbs than the traditional version of Atkins. "We can pace the weight loss at 2 lbs. a week, so that it won't affect her breast milk and she gets adequate protein from chicken, fish and some meat," her nutritionist, Colette Heimowitz, told "Extra" in January.

"Kim is staying on track with her weight loss progress and taking it day by day," a source recently told E! News. "She is very busy with Saint and North [West] in between of taking care of herself and being a wife. Running around with the kids definitely helps with shedding some weight, and she has been working out and eating healthy."

Clearly, all of her hard work is paying off big time.
