The 32-year-old, who is engaged to former NFL player Eric Johnson, gave birth to her daughter on May 1 and said that she gorged on calorific treats during the pregnancy, which lead to her piling on the pounds, reported Contactmusic.
"I let myself indulge in everything I wanted because it was the first time I was ever pregnant, and I wanted to enjoy it. I didn't know the weight didn't all come off with the baby," she said.
Simpson has embarked on an exercise regime but she said that she wants to show people that it's not easy to bounce back after having a baby and is determined to lose weight in a healthy way.
"My body is not bouncing back like a supermodel. I'm just your everyday woman who is trying to feel good and be healthy for her daughter, her fiance and herself," she added.
