Hilaria Baldwin has lost 18 pounds.
The 31-year-old beauty has lost the impressive amount in just ten weeks and credits her success to avoiding stress.
She said: "I gave birth about 10 weeks ago, but I'm not trying to lose the baby weight.
"I've come to a point in my life where I'm not trying to be skinny, I'm just trying to be healthy, and I've found that if I don't really stress about it, the weight kind of just comes off."
Hilaria - who has daughter Carmen, two, and newborn son, Rafael with husband Alec Baldwin - also puts her success down to coconut water.
She shared: "I started drinking it religiously when I was pregnant with Carmen to soften the early contractions I had throughout my pregnancy.
"My doctor wanted me to drink Gatorade, but I prefer not to drink anything with artificial colours, and coconut water is supposed to hydrate just as well.
"I'm totally on the coconut bandwagon right now because I'm breastfeeding my son and it's also supposed to help with milk production."
And after choking on a chip as a young girl, she avoids snacking on anything similar, preferring fruit and vegetables.
She told Cosmopolitan magazine: "To this day, I don't really like chips or crackers or anything like that. I'm very into textures. I don't like popcorn because it reminds me of packing material."
