Look at those baby blues!

Nick Lachey and his adorable son Camden show off their matching blue eyes on the cover of the singer's new lullaby album, "A Father's Lullaby."

The 98 Degrees star co-wrote four new songs for the album, which was inspired by his super cute five-month-old with wife Vanessa Lachey.

"When I first learned that I was going to be a father, I was inspired to create a special tribute to my son," Lachey said in a press release. "Music has always been an incredibly significant part of my life and a meaningful way in which I express myself."

"Creating this album allowed me to further connect with Camden while also sharing the experience with families who are on a similar journey of welcoming a new life into their world," he adds.

The album will be available on iTunes March 13.
