Vanessa took to Instagram on Monday to share a snapshot from the b-day bash, showing off her and her son's custom shirts -- featuring Superman's logo, but with a 'C' in place of the traditional 'S' -- and his incredible, three-tiered superhero cake!
"#HappyBirthday sweet angel boy! May ALL your wishes come true!" the proud mom captioned the cute photo of her son blowing out his candles. "We LOVE you sooooooooo much! #CamdenJohnLachey #SuperCam."
Nick, 42, and Vanessa, 35, who tied the knot in 2011 in a ceremony on Richard Branson's private island in the British Virgin Islands, welcomed Camden on Sept. 12, 2012. The couple also share a 1-year-old daughter, Brooklyn Elisabeth.
