Looks like Bronx Mowgli is getting a kid sister. A rep for Ashlee Simpson has confirmed to Us Weekly that the singer/actress and her new husband, actor Evan Ross, are expecting a baby girl. This will be the first daughter for Simpson, who is mom to 6-year-old Bronx, her son with ex-husband Pete Wentz. She will also be the first child for Ross, who is the son of singing legend Diana Ross. Bring on the "Baby Love." According to Simpson, Bronx is ready to play big brother. The tyke already has a half-brother, Pete Wentz's 5-month-old son, Saint Laszlo. "He wanted to have a sister, so he’s really excited," Simpson told Us. "He's got a little brother. Now he's going to have a little sister!” Now comes the fun part: Guessing the name. Encino Nahla? Brooklyn Elsa? Beverly Alice?
