Another Backstreet baby is here!

Congratulations go out to Kevin Richardson, 41, and his wife Kristin, who just welcomed their second son.

The Backstreet Boys singer announced the happy news on Facebook"Special delivery! Another Richardson boy... At 3:05am Wednesday morning (7/10/13), Maxwell Haze Richardson decided to join the party. He is a stout 9 lbs. 8 oz. / 23 inches long. Love! Love! Love!" Kevin and Kristin's son Mason Frey was born in July 2007.

Kevin’s bandmates have also been busy making Backstreet babies. A.J. McLean welcomed a daughter in November, and Howie Dorough welcomed a son in February. Also in February, Nick Carter announced his engagement. So it's possible he'll soon have the next child to add to the BB baby band.

Congrats to Kevin and his growing family!
