Emily Grace Stanley joins older sister, 2-year-old Sarah, and older brother, 4-year-old Colin. Stanley, 59, also has a 17-year-old son, Evan Shane, from a previous relationship.
"Erin and I are once again blessed with the addition of Emily Grace to our family," Stanley, 59, told Us Weekly in a statement. "I'm not sure she can sing, but her first screams let me know she's definitely Daddy's girl."
Stanley recently wrapped a North American tour with KISS.
