"We are incredibly proud to announce the birth of our beautiful baby boy, Camden John Lachey," the couple said in a statement to E! News about the delivery.
"Born today at 6:54 p.m., he came into this world at 8 pounds, 9 ounces and 21 inches. Love has truly been redefined for both of us."
"It's a good idea to put all ur baby stuff together ahead of time AND try it out. Then ur familiar," Vanessa had just tweeted on Monday.
And she wasn't kidding!
"Baby is RUMBLIN!!!" Vanessa tweeted on Sept. 6. "I don't know if it's the food I'm eating or the fact that @NickSLachey is screaming at the #Bearcat game."
Obivously the little guy was just warming up for his own kickoff.
Congrats to Nick and Vanessa!
Meanwhile, Kristin Cavallari sent out the following tweet early Thursday morning.
"Apparently Camden is a popular name!" she wrote.
The former Hills star and fiancé Jay Cutler welcomed their own little Camden just last month.
