Billy Corgan is a dad! Us Weekly reports that Corgan, 48, and his girlfriend Chloe Mendel, 22, welcomed a son, Augustus Juppiter Corgan, into the world yesterday. Mendel is the manager of Corgan’s Chicago tea house Madame ZuZu’s. Augustus is Corgan’s first child, making him a new dad. Maybe he will celebrate by listening to Macklemore’s lame New Dad anthem. Probably not.
