The 31-year-old star already has seven-year-old son Bronx with ex-husband Pete Wentz and 10-month-old daughter Jagger with spouse Evan Ross, and though she isn't ready to add to her brood again just yet, she is planning more kids in the future.

She said: "It's a blessing. Kids are the best.

"I would love to have number three. I'm not ready for that just yet, but I definitely want more."

And having her daughter has only made Ashlee love her 27-year-old husband more.

She said: "Having a child with the person you love is just amazing. She's a little us.

"Evan is an amazing dad, so it's fun to get to see each other grow in our love and our love for her."

The blonde beauty loves spending time with her sister Jessica Simpson - who has kids Maxwell, four, and Ace, three, with husband Eric Johnson - and knows she can always call on her if she needs advice.

She said: "We get all our kids together for a fun time. Bronx hangs with Maxwell and now Jagger is here they're all interested in her as the little baby. It's very cute.

"Jessica is an incredible mom, so both of us give each other advice. If I have a question about parenting, I'd definitely go to her."

Shortly after welcoming Jagger into the world, Ashlee returned to work, voicing a character on 'Space Dogs: Adventure to the Moon' and did so because she knew it would garner her approval from her son.

She told Britain's HELLO! magazine: "He's always like, 'Mum, you should do a voice' so he was happy I did that. I'd just had Jagger so I brought her to the studio, so it all worked out.

"I knew it would make my kids happy."
