The 32-year-old brunette has posted a picture of her in her underwear less than a day after she welcomed her and Alec Baldwin's third child, Leonardo.

Captioning the picture on Instagram, she wrote: "I took this yesterday when Leonardo was about 24 hours old. I did the same thing right after Rafael was born. It always makes me a bit nervous to do something like this, but I feel that in the age of such strong body shaming, I want to do all that I can to normalise a real body and promote healthy self esteem.

"Many of you know that I love to show the process of life's experiences on the body and I am a firm believer in how a good diet and the right balance of exercise make us happy, healthy, and strong. So from here on, I want to dedicate the majority of my #366daysoflivingclearly #hilarialcm daily posts to getting back in shape and I invite you to do it with me. (sic)"

And the mother-of-three - who also has Carmen, three, and 14-month-old Rafael with her husband - answered a few questions about her pregnancy whilst insisting she didn't use any kind of filter on the picture.

She added: "Common questions last time were: Did I have a c section?: No, I pushed him out ... Where are all the pads for bleeding?: I took them out briefly to snap this pic as there is a limit to how much you need to see ... Where am I?: in the hospital room bathroom #glamour ... Oh, and no filter. Just brightened it up a bit. (sic)"
