Keen for more publicity Jessica has been telling people she will name her unborn son, Ace. US Weekly reports "[She's] told people she's going to name the baby Ace!" the source told Us Weekly. Simpson, 32, is already mom to 10-month-old daughter Maxwell. The singer hasn't yet revealed how she and Johnson, 33, decided upon the name, however. Yip, the next kid is the ace up her hole, not like the first unplanned one. No this second unplanned kid has potential. This kid could be the next Pet Detective.
