It’s another boy for Good Charlotte guitarist Billy Martin! The musician and his wife Linzi welcomed their second son today, September 14th. Zander Jace Martin joins big brother Dreavyn Kingslee (3.5) in jazzing things up for the family. Martin took to Twitter to announce his baby news, saying, “Welcome to the world Zander Jace Martin. He was born this morning, both he and Linzi are doing great! What an amazing day.” Martin will get to spend a few more amazing days focusing on his newly expanded family before the band heads off to the land down under on tour.
