Mrs. Eric Decker's already shed her baby weight!

Country cutie Jessie James Decker showed off her super tiny waist in a new Instagram pic on Monday.

The blonde beauty -- who welcomed her a baby girl, Vivianne Rose Decker, with Eric earlier this year -- is already back in her size 25(!) jeans.

"Taking my sweet time but man do I feel proud today! I actually fit into my size 25 Frankie b jeans! Now trust me this is a good angle I took the pic in! Ha. Anyway-All I have been doing is watching the sweets and 20 min of cardio everyday!! 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!! don't stress over it! 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! Love y'all ps yes I suitcase is out to pack for Jersey :)))," she captioned the candid photo.

We gottta hand it to the 25-year-old --- her post-baby bod's looking amazing!


It also seems like the "Eric & Jessie" stars are really enjoying parenthood. Just last week, the "Wanted" singer shared a picture of her and her baby girl rocking matching jerseys to support the sexy footballer.

"Matching!!! Let's go see daddy!!!," she captioned the sweet snap.
