Ashlee Simpson and husband Evan Ross have welcomed their first child together, a baby girl. Simpson gave birth to her second child on Thursday, July 30.

Simpson already has a 6-year-old son, Bronx, with her ex-husband Pete Wentz. This is Bronx’s second sibling, as Wentz welcomed a son, Saint Lazslo, with his girlfriend Meagan Camper last year.

A source confirmed Simpson, 30, gave birth to Us Weekly but her daughter’s name has not been revealed just yet.

Simpson has talked about telling her son about her pregnancy “early on,” explaining, “He wanted to have a sister, so he’s really excited! He’s got a little brother. Now he’s going to have a little sister!"

Simpson married Diana Ross’ son in August 2014 at the singer’s Greenwich, Connecticut home. She revealed she was pregnant in December of that same year.

Ross has said of having a family with Simpson, “I would love to [have kids]. As many as possible.”
