Good Charlotte Rocker Is a Dad!
Dreavyn Kingslee Martin was born on Jan. 26 in Pasadena, Calif. He is the first child for the couple.
"Mom is doing great, baby is healthy," Martin tells PEOPLE. "I couldn't ask for anything more."
Adds Martin: "It is hands down the most amazing thing that has ever happened in my life. We can see so much of my wife and I in him already!"
Martin, 27, is the second member of Good Charlotte to become a father – singer Joel Madden and girlfriend Nicole Richie welcomed daughter Harlow a year ago.
After announcing Linzi's pregnancy last September, Martin told PEOPLE they were planning an Alice's Adventures in Wonderland-themed nursery.
Martin and his wife Linzi, 25, will celebrate their first wedding anniversary – and ninth year as a couple – on March 1.
Up next for Martin, an accomplished painter and illustrator with his own T-shirt line, Level 27: a new Good Charlotte album followed by a children's book that he wrote and illustrated called Damious McDreary: A Boy and his Bat, which will be released this fall.
