The 31-year-old Fashion Star mentor made an appearance on The Tonight Show With Jay Leno Monday where she finally put rumors to rest about her big baby bump. “No, it’s not twins,” Simpson said. “I know it looks like it.”

She went on to add that she and her beau Eric Johnson are having a baby girl. Aww!

Despite the extra baby weight, the mother-to-be isn’t letting that get in the way of her fabulous style. Adding that she’s “waddling at this point,” Simpson pointed out that she was wearing sky-high heels. “It’s a lot of weight to carry on six inches!”

Jess, who recently bared all for ELLE, says she’s not quite ready to give birth. “Labor is really going to hurt. I have so much respect for my mom and all the women across the world,” she said.
