London, Feb 21 : Jessica Simpson, who is reportedly 5 months pregnant, has already picked up a baby name for her yet to be born baby: Ace.

The 32-year-old actress and her former NFL player fiance Eric Johnson have reportedly told their friends what they are going to name their impending new arrival, but haven't explained the inspiration behind the name, the Daily Mail reported.

The moniker made famous by Jim Carrey's character in the 1994 movie `Ace Ventura: Pet Detective,' tends to be a boy's name and means "one" or "expert."

The couple are already parents to nine-month-old daughter Maxwell Drew. (ANI)
