The mother is a New Jersey native he met last year in Las Vegas while in town for a gig, reports TMZ, which broke the news Tuesday.
"I'm proud I'm a father," Delvecchio says. "I am excited to embark on this new part of my life."
According to TMZ, the mother, who is 26, filed court documents in New Jersey to formally establish paternity. However, Delvecchio, 33, has already taken a paternity test that proves he is indeed the father.
The baby is reportedly a few months old and living with her mom.
