Washington, Dec 3 : Mother to be Jessica Simpson is sure that she's having a girl, even though she doesn't definitively know the baby's sex yet.

She insists that even if it's a boy she'll dress him up and put him in tutus.

"I think it's a girl. if it's a boy, I'll put him in tutus," People. com quoted her as saying.

However, her fiancé Eric Johnson disagrees and believes that they will be having a boy.

"I think it's a boy. We're pretty much at a standstill there," Johnson said.

The two intend to end the speculation soon and find out whether their child is a boy or a girl.

"I don''t think we can wait. Jessica is too honest about everything, she needs to know. I don''t think she can hold that secret to herself," he said. (ANI)
