Camden's a cutie!

Overjoyed new parents Nick and Vanessa Lachey welcomed their first child together, son Camden John Lachey, on Sept. 12.

And on Monday Oct. 1, the spouses of 14 months shared the first-ever public snapshot of their special little guy via Twitter.

"[Nick] and I are honored and humbled to introduce you to the new Love of our lives, Camden John Lachey," Wipeout hostess Vanessa, 31, wrote beneath a precious pic of Camden -- with dark hair and pouty lips -- resting on his mom's lap.

Just five days after his son's birth, proud papa Nick, 38, admitted via Twitter that fatherhood had him completely overwhelmed -- in a good way!

"Camden is easily the most amazing thing that has happened in my life. Vanessa Lachey and I are truly blessed," he wrote.

Vanessa is just as bowled over. "When I look over and see my husband and my son, my heart melts," wrote Vanessa, who wed her man on Necker Island in July 2011. "I am so in love with these two! Count Your Blessings.
