The 31-year-old singer and the 'Hunger Games' actor, 27, welcomed their daughter, Jagger Snow, into the world three months ago, and she feels really lucky that he loves being a hands-on dad.

She said: "He is the cutest dad ever. He's just so there. It's amazing."

Evan also says he and the blonde beauty are the perfect team when it comes to parenting.

He explained to Us Weekly magazine: "Ashlee likes the mornings, so I'll take the night. It works out really well."

It was recently revealed Ashlee - who also has six-year-old son Bronx with ex-husband Pete Wentz - and Evan "couldn't be happier" with their new family unit and are spending as much time together as possible.

A source said: "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."
