It's been five months since Jessie James welcomed her first child with husband Eric Decker.
But the singer-songwriter-reality TV star has already shed most of her baby weight, as evidenced by the first photo in the following gallery.
"Taking my sweet time but man do I feel proud today!" James wrote as a caption this week. "I actually fit into my size 25 Frankie b jeans!"
James did qualify the images with the following disclaimed, however: "Now trust me this is a good angle I took the pic in! Ha."
Does the beauty have a secret for weight loss?
"All I have been doing is watching the sweets and 20 min of cardio everyday!" she recently said. "What's crazy tho is I weighed 13 lbs lighter than this before I got pregnant! I feel great and healthy! It's been almost 5 months since I have my baby girl. It took me 9 to gain 55 lbs!"
The Eric & Jessie: Game On star concluded by encouraging fellow mothers not to be concerned about losing the extra baby weight.
"Don't stress over it!" she wrote. "You can do it and at your own pace! There was no way I was going to drop all the weight at once nor should it be a focus. The focus is on being healthy and feeling good!"
Hear that, Kim Kardashian?
