Like father, like son!

Nick Lachey poses with his 5-month-old baby boy Camden on the cover of his new album of lullabies, and we can't believe how much the little cutie looks like his daddy!

Titled "A Father's Lullaby", the album features four songs written by the former boy bander, which were inspired by his own journey into fatherhood.

It will be available on iTunes March 13, and in stores starting in April!

Bedtime songs aren't the only thing he's focusing on, though!

The singer will release a new album titled "2.0" with his 98 Degrees bandmates in May.

Too cute!
