The reality star was pictured enjoying a holiday to Mexico with fiancé Roger Mathews and their daughter Meilani, who was born last July.
After seeing the images, the MTV star posted a message to her official website under the headline, "Love yourself."
She said: "I want to sit here and say that I'm embarrassed by these pictures but honestly I'm not. I'm a new mum that loves to work out but also loves food as well."
Jwoww – real name Jenni Farley – went on to say that she'd been at a friend's wedding, held at an all-inclusive resort, and she decided to indulge and treat herself.
"At the end of the day I am not perfect and neither is my body… I will always try to eat healthy and take @310nutrition supplements and consistently work out but I'm also a human and I love being me and I love my life.
"I will never try to follow the trend of being stick thin. I follow the trend of what I love in life… And what I love is me. Everyone love yourself and consider yourself #flawless."
Fans, however, were quick to tell Jwoww she should definitely not be embarrassed by her figure, with one saying: "You're always beautiful and always will be. Don't think different. And don't let anybody tell you anything different."
Another said: "Never be embarrassed by the body that gave your child life!"
