Nick and Vanessa Lachey took to the beach in Cabo San Lucas, Mexico, together on Tuesday. The couple was joined by a group of friends as they relaxed with beers and helped their 1-year old son, Camden, build sandcastles. Vanessa stayed close to her little one while laying out in a black one-piece, and Camden looked absolutely adorable with his printed swim trunks and ponytail. Nick — who we can all agree doesn't look much different from his 98 Degrees heyday — brought his family down to Mexico after spending Christmas in his native Cincinnati, OH. Before heading home for the holidays, though, The Sing-Off host wrapped up the fourth season of the show with a fitting performance of "I'll Be Home for Christmas" with his fellow 98 Degrees bandmates.
