Jessica Simpson on Eric Johnson: The BEST Dad » Gossip

Jessica Simpson and Eric Johnson welcomed their daughter Maxwell Drew on Tuesday morning, and the new dad is doing all he can to take care of mom.

"Eric is amazing. He is involved with every single thing, and Maxwell adores him," a source close to Jessica says. "Whenever she cries, he picks her up and holds her in his arms, and [Maxwell] immediately stops crying."

"It's just the cutest thing."

In March, Simpson predicted that her fiancé would be an "unbelievable" father because he's patient and a born leader ... whatever that means.

In any case, she was totally right!

"He is the best dad already," the source continues. "He is also super attentive and taking amazing care of Jessica throughout. It's incredible."

All very good to hear.
