Simpson gave birth to Jagger Snow Ross, her first child with Evan Ross on Thursday, July 30. The singer first became a mom 6 years ago with ex-husband and Fall Out Boy band member Pete Wentz.

Jessica Simpson’s sister first showed a preference for unique names when she named her son Bronx Mowgli Wentz. “The Jungle Book was something that me and Ashlee bonded over,” Wentz told Ryan Seacrest in 2008, explaining the choice of Mowgli for a middle name. “We came up with the idea Bronx … It’s kind of cool to just leave the narrative what it is.”

Simpson’s son’s initials unintentionally spell out BMW, the luxury automotive company. Less glamorous, JSR stands for Java Specification Request, which is a technological proposal to make additions to the computer software Java’s platform.
