Jessica Simpson's bun in the oven is destined to be a hole in one, if the name she's reportedly selected tells us anything.

A source close to the singer and "Fashion Star" mentor revealed to Us Weekly that she and fiance Eric Johnson, a retired NFL tight end, have selected Ace as the baby's name. Simpson has not yet disclosed her reason for choosing the name.

Simpson and Johnson had their first child, Maxwell, in May 2012. Maxwell, now 10 months old, was named after Simpson's mother's maiden name and Johnson's middle name.

Simpson revealed she was pregnant for a second time this past December, confirming the news via Twitter on Christmas Day. She was spotted out and about with Maxwell on Monday.

We'll see how conservatively Simpson decides to dress throughout this second round. She made headlines during her first pregnancy for wearing form-fitting, scanty outfits not commonly associated with maternity dress.
