The singer tied the knot with Vanessa Minnillo in a private island ceremony earlier this month, but said that life hasn't changed that much since their big day.
'It doesn't feel any different, which I think is a great thing. I think that means it was good to begin with,' he told People magazine. 'We're just very comfortable and happy in our life together, so now we are back to work and back to the routine.'
Lachey is set to start promotion for the third season of The Sing-Off, but admitted that he is excited about his wife's new gig as a co-host on game show Wipeout.
'I am begging to go on that thing,' the 37-year-old said. 'I've asked her, 'When is friends and family day?' When they get into production on that in the fall, I hope to go out there and take a turn at it and get a little muddy.'
