The guitarist shared the happy news with fans on Twitter on Thursday (July 5) and revealed that he named his son after legendary heavy metal band Black Sabbath.
"VALHALLA JAVA ALMIGHTY BLACK LABEL!!! SABBATH PAGE WIELANDT WYLDE Has Come to Join The Mother Chapter!!!!" Wylde tweeted.
Wylde has turned to his musical heroes for inspiration in naming his children before, having called his older son Hendrix.
The musician is perhaps most famous for his decades collaborating with Ozzy Osbourne in the studio and on tour.
Wylde is currently fronting his own popular heavy metal band Black Label Society, whose last album The Song Remains Not The Same was released in 2011.
