Camden's a big brother! Vanessa Minnillo and Nick Lachey have welcomed their second child. The proud mom shared the news on her official website on Tuesday, Jan. 6.

"She's HERE!!!! Nick, Camden and I are SO excited to announce the birth of our sweet, beautiful baby girl, Brooklyn Elisabeth Lachey! She was born January 5th, 2015 at 5:17pm. She weighed in at 7 pounds 15 ounces, is 21 inches long and has already won over all of our hearts," Minnillo, 34, wrote.

"I have been dreaming of this moment for as long as I can remember, the day I was going to meet my little girl. A friend recently told me how magical today was going to be because it's the day I would meet my best friend," she continued. "I can't even begin to tell you how it felt to hold her in my arms for the very first time. Mommy, Daddy and big brother Cam love you so much already, Brooklyn! Thank you to everyone for your love and support, it means so much to our family. Xx, The Lacheys."

Lachey announced the couple were expecting baby No. 2 via Twitter in July. "Can't think of a better way to celebrate 3 years of marriage to my beautiful @VanessaLachey than this! #family," the 41-year-old captioned a pic of "It's a girl" written in the sand.

Minnillo and Lachey tied the knot on Necker Island in July 2011. In May, the former 98 Degrees singer — whose first wife Jessica Simpson is also remarried with two kids — gushed about his wife's parenting skills.

"My wife's maternal side is a new dynamic to her personality," Lachey told Parents magazine. "It's definitely made her even sexier." Minnillo added: "I knew the man I was going to marry was not only a great man, a good friend, and a family guy, but he was going to respect and treat me well and be an amazing father and role model to our children. That's Nick." See adorable photos of Lachey and Minnillo here.
