The Transformers star admits she is so "in love" with baby Noah that her husband Brian Austin Green is a little jealous - and now she wants another kid.
She tells U.S. news show Extra, "I'm just happy I got the opportunity to do it (be a mum). I was very overwhelmed with the intensity of the emotions I felt when I had him... and Brian is jealous because I love him so much.
"I want more kids. I'm so tired (and) I don't know if my body could do it right now, but if it happens, it happens. He (husband) wants a little girl."
