and Eric Johnson welcomed their daughter Maxwell Drew
on Tuesday morning, and according to a source, the baby is already a daddy's girl.
"Eric is amazing. He is involved with every single thing, and Maxwell adores him," the source says. "Whenever she cries, he picks her up and holds her in his arms, and she immediately stops crying. It's the cutest thing."
Maxwell also has dark hair, just like her daddy.
In March, Simpson predicted that her fiancé would be an
"unbelievable" father because he's patient and a born leader. According to the source, she was absolutely right.
"He is the best dad already," the source continues. "He is also super attentive and taking amazing care of Jess. It's incredible."
