Rocker Billy Corgan introduced fans to his 'son' at an intimate concert in Los Angeles on Saturday (17Apr10).
Corgan and his new-look Smashing Pumpkins performed a free, hour-long set at makeshift venue Space 15 Twenty to mark Record Store Day and the frontman had fans scratching their heads when he introduced them to his masked son, Jason.
The rocker explained, "You may have seen a recent article on me in Rolling Stone that talked about how I've been affected by not having children. Well, since then I've found out that I do have a child."
Jason, who was masked to protect his privacy, told Corgan, "You're the worst dad in the world!"
Corgan made it clear the whole thing was just a joke, but he had children on his mind later in the set when he performed ukelele song Baby, which he dedicated to friends who'd recently given birth to daughters, both named Talulah.
