Two weeks after Nick Lachey and wife Vanessa Minnillo welcomed son Camden John, the proud new papa took a night off from daddy duty -- to support his brother, Drew Lachey, at Monday's Dancing With the Stars: All Stars premiere.
"I don't know if he was here more to support me or more to just get a night out of the house!" Drew, 36, joked to Us Weekly of his older brother, 38, who became a first-time dad on September 12. "I've been that new father twice, so I know how it is!"
Supporting Drew and his pro partner Anna Trebunskaya as they performed the foxtrot, Nick was able to show off his fatherly instincts while bonding with his niece, Drew's six-year-old daughter, Isabella.
"To be able to do this in front of your family to show them, 'Yeah, this is what daddy does' - I take a lot of pride in it. I still teach kids back in Cincinnati, so this gives me a great platform to show them, 'Look guys, I'm still doing this!' It's a win win across the board."
Drew told Us his daughter, son Hudson, 2, and wife Lea have already been introduced to baby Camden and the extended Lachey family is getting along famously. "My son, before he flew out here, was running around saying, 'We're going to LA to see Uncle Nick and Aunt Vanessa and the baby!' It's great. The Lachey family is expanding and the more the merrier."
Two-week-old Camden is "absolutely adorable," reports Uncle Drew. "He doesn't look like Nick as a baby, he looks like Nick now!"
