Nick Lachey finds his wife "sexier than ever" since they had a child together.
The 40-year-old singer loves watching spouse Vanessa caring for their 19-month-old son Camden and says the little boy has brought out a new side to her personality.
He said: "My wife’s maternal side is a new dynamic to her personality – and it’s definitely made her even sexier."
The couple – who married in July 2011 after five years of dating – dote on their little boy but also treasure their alone time when Camden goes to bed.
Vanessa explained to Parents magazine: "We put on some music or a favourite TV show, pour a glass of wine, have dinner – that’s our ‘alone time’
"When you’ve got the little one between you, it’s not as romantic as when the two of you are alone."
And it doesn’t matter where in the world they are, the pair always stick to a schedule to get their son to sleep by 7.30pm.
Vanessa said: "Whether we’re in New York or Cincinnati or on vacation, as long as he gets his story, sound machine, and song, he’s good."
Both Vanessa, 33, and Nick are keen to have more children, but will wait a while so their offspring don’t have to "share" friends – though they won’t leave it too late.
Nick said: "You don’t want kids to have to share the same group of friends."
Vanessa added: "But you don’t want them so far apart that they have nothing in common."
