Nick and Vanessa Land with Camden

Those look like the smiles of some happy parents. The baby must have behaved on the plane!

Beaming new parents, Nick Lachey and Vanessa Minillo arrived at LAX with their son Camden last night. Nick carried the family dog in a doggie-duffel-bag, while Vanessa cradled the blanket covered baby against her chest.

We've never seen these two look happier! Or are they just punch-drunk from new parent sleep deprivation? Hard to say.
