Jessica Simpson says that she is encouraged by how her body is changing following the birth of daughter Maxwell in May.

And the 31-year-old reality star turned fashion mogul told her Twitter followers that she is moved by how being a spokesperson for Weight Watchers and her journey is having an effect on her life.

"What we put in our bodies mirrors our Self-Worth!" Jessica wrote. "#INSPIRED."

The proud new mother has said that she wants to be a good role model for her little one and is going to take her time in losing the weight rather than crash dieting.
