Jessica Simpson and Eric Johnson have reportedly chosen a baby name for their second bundle of joy following claims that the unborn baby is a boy.

The 32-year-old, who has a 10-month-old baby girl, confirmed her second pregnancy on Christmas day in a Weight Watchers commercial. A source claims Simpson and her fiance have agreed on an unusual baby name, according to Us Magazine.

"[She's] told people she's going to name the baby Ace!" the source told Us.

The couple is no stranger to unusual baby names as their daughter, Maxwell Johnson, also has a non-traditional name which holds a lot of "meaning." They reportedly also considered Zinfandel as her first name but ultimately went with Maxwell.

"They tossed around a lot of names, including some wacky ones like Zinfandel, but couldn't agree on anything," a family friend previously told In Touch Magazine.

"They're going to call her Maxwell, Maxi for short. Maxwell is Eric's middle name, and also his beloved grandma's maiden name. Jessica wanted a name with meaning," the source added.

On January 18 a source claimed Simpson and Johnson, 33, had discovered the sex of their second child.

"[Jessica] found out this week after a check-up at the doctor, who asked her if she wanted to know the sex of the baby ... she immediately said yes and when the doctor told her it was a boy she screamed with joy!" a source told RadarOnline.com.

"It's Jessica's dream come true, she prayed she was having a boy," the source continued. "What with everything going on in her personal life, and her problems with her father, this has given her something to smile about."

Simpson's father, Joe, was recently forced to deny rumors surrounding his sexuality after being embroiled in a bizarre sex scandal. The 52-year-old former pastor is also currently facing a messy divorce battle against Simpson's mother Tina.

The singer and Johnson, who is a retired NFL player, have reportedly put their wedding on hold until after the birth of their second child.

"She was so happy that Maxwell is getting a little brother because that's something she always wanted when she was growing up," the source added.
