Simpson gave birth to an adorable baby girl on Thursday night at a Los Angeles hospital. A close to the pair said, "Their whole family was around to support them. Evan was very emotional and loves Ashlee so much. He did not leave her side and wanted to go through this with her every step of the way. He can't wait to be a dad. He would do anything for Ashlee and now this baby girl. Ashlee is doing great and can't wait to get home to to be with her family."
This is Evan’s first baby, while Ashlee is also a loving parent to 6-year-old son Bronx with ex-husband Pete Wentz. This is the third grandchild for Evan’s superstar mom, Diana Ross.
The couple announced they were expecting a baby in December after getting married in August last year.
