Jenna Fischer admits that she is "not getting any skinnier" although she is breast-feeding her baby.

The Office star gave birth to her son Weston just four months ago. However, she claims that she is not like other celebrity mothers who seem to snap back into shape post-pregnancy.

Jenna told Us Weekly that her weight loss is going at a slower pace but that she is fine with that.

"Let me please stand in solidarity with all of the women who are not a size 2, six weeks after leaving the hospital," the actress said.

"I thought, you read all of the stuff in magazines like, Oh I breastfed my baby and I am so skinny now.' I am breast-feeding my baby and I am not getting any skinnier!

"I think I'm just going to be a little bit bigger for a little bit longer, and that's fine with me."

The 37-year-old tied the knot with screenwriter Lee Kirk in July 2010 and said that becoming a mother has changed her life in the most fabulous way.

"I love being a family," she gushed. "I love going from two people to three people, and it has deepened the bond between me and my husband. We love being together, the three of us. Our little unit."
