He won Dancing with the Stars 2 with Cheryl Burke, but Drew Lachey may soon have another partner to dip and twirl. "Isabella has these feet with arches already kind of developing," he says of his 2-month-old daughter. "She's already got dancer feet! I wouldn't be surprised if she follows in her mom and dad's footsteps."
As PEOPLE reports in its new issue, the former 98 Degrees singer and his choreographer wife, Lea, have found their footing as parents since the March 23 birth of Isabella Claire. "I am in charge of changing diapers," says Drew, 29. "And I'm an expert swaddler. I have mastered that very quickly."
Says Lea, 29: "He's amazing and gentle and soft. He has this very particular voice that he uses just with her. That's my favorite thing, to watch him with her."
The new dad plans to write a lullaby for his little girl, but in the meantime "she likes these low hums, and I'll sing anything to her: Sly and the Family Stone, opera," Drew says.
She's also into pop music. Before the baby was born, while Drew and Lea were listening to a preview of his brother Nick's new album, "she just went nuts," says Drew. "She was dancing in the belly like no one's business!"
Uncle Nick, whose new album What's Left of Me debuted at No. 2 on Billboard's Top 200, is a fan of hers too. "She is an angel – there's never been a more beautiful baby," says the older Lachey, 32. "Thank goodness she looks like her mom."
Nick has even set up a crib at his house in case his goddaughter ever needs a babysitter. "He's set! I don't think he'll enjoy the pumping that much," Drew jokes, "but once he gets over the soreness of the nipples, he'll be all right!"
