Shooter Jennings, Drea de Matteo Welcome Baby Boy!

Congratulations to Shooter Jennings and fiancée, actress Drea de Matteo, who have announced the arrival of their second child, a son who will carry on the family name.

Shooter broke the news via a Twitter post yesterday (April 7), tweeting, "Waylon Albert 'Blackjack' Jennings has arrived folks!" He later thanked well-wishers for "all the kind words" adding, "we're super lucky to have so many kind friends."

'Blackjack' is the third in the Jennings line to carry the Waylon name. Shooter was born Waylon Albright 'Shooter' Jennings after his father, country music icon, Waylon Jennings. 'Blackjack' joins his big sister, three-year-old Alabama Gypsy Rose.

Shooter and Drea were engaged in 2009, when the singer popped the question while on stage at a concert in Utica, N.Y.
