According to E! singer/actress Ashlee gave birth on Thursday evening (30 July) and "can't wait to get home" with her new addition. Congrats!
A source revealed: "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."
So far the couple are yet to confirm their daughter's arrival and any other details surrounding her birth.
News Ashlee and Evan have welcomed their first child together comes after the 30-year-old was spotted sporting a HUGE baby bump.
Earlier this week, Ashlee had looked like she was going to pop any minute, heading out with Evan in LA. The couple couldn't have looked more loved-up, with Evan (son of legendary singer Diana Ross) planting a kiss on his wife as she cradled her baby bump.
While their daughter's arrival is Evan's first child, she will be Ashlee's second. She is already mum to son Bronx, six, from her first marriage with Fall Out Boy star Pete Wentz.
Reports speculated Ashlee was pregnant again in December last year, with the blonde beauty confirming she was expecting a daughter back in February.
She admitted she had wanted to find out the sex of her baby so she could get started on preparing its nursery. Aw!
Her and Evan's baby joy comes almost one year after the couple tied the knot. Ashlee and Evan married in Connecticut at Diana's estate on 30 August 2014.
Until now they had kept their nuptials private, but Evan shared a series of his and Ashlee's wedding photos to Instagram earlier this week.
And it's fair to say their big day looked just dreamy!
