Ashlee Simpson and Evan Ross ''couldn't be happier'' with their baby girl.

The 'Pieces of Me' hitmaker and the 'Hunger Games' star welcomed daughter Jagger Snow into the world earlier this month and are reportedly spending as much time together as a family as they can.

A source told E! News: ''Ashlee and Evan couldn't be happier.

''Right up until Ashlee gave birth Evan was playing shows quite frequently, working hard on his album but since Jagger was born he's put his music on hold and has been spending most of his time with Ashlee and the newborn. Only family and a few friends have seen Jagger but they say she's adorable.''

And Ashlee's father Joe has admitted he is smitten with the ''precious'' little girl, whilst he also revealed he and his ex-wife Tina were both present in the delivery room.

He said previously: ''Jagger is precious. She's quiet and sweet and she's such a happy baby. She's barely two weeks old. The apple of her papa's eye. She's beautiful. She looks like her mommy and daddy.

''I got to take a picture of my little granddaughter the day she was born! In the room with the baby, it was great to watch them have that moment. And, you know, grandparents, we were standing back. What a beautiful thing to watch.''
