Jessica Simpson already picked out the name for her second child with fiance Eric Johnson and revealed it to her friends and family, according to an Us Weekly source. 

The singer and fashion designer is already mother to 10-month-old daughter Maxwell Drew Johnson. It was confirmed in January that her second child will be a boy and the insider said, "[She's] told people she's going to name the baby Ace."

Last year Simpson revealed that she decided upon her daughter's name as a tribute to both her family and Eric's. Maxwell is her husband's middle name and also his grandmother's surname, and Drew is Simpson's mother Tina's maiden name. 

Simpson announced her second pregnancy via Twitter on Christmas Day. The 32-year-old tweeted a picture of Maxwell Drew sitting in the sand near the words "BIG SIS" drawn in the sand. She captioned the picture, "Merry Christmas from my family to yours!" 

Simpson reportedly "screamed with joy" when she learned she was having a boy with her fiance. A close family source told Radar Online, "It's Jessica's dream come true, she prayed she was having a boy."

Simpson and Eric celebrated Valentine's Day, Feb. 14, by going out for lunch at Ivy at the Shore in Santa Monica, Calif.
