Ex-Tonic Singer Emerson Hart, Wife Have a Baby

Musician Emerson Hart and his wife Nicole have a new addition to the family – daughter Lucienne Elizabeth, born on Oct. 4, the couple tells PEOPLE.

Lucienne weighed in at 7 lbs. 11 oz., and is doing well at home in Nashville, a rep for Hart says.

Hart, 38, the former frontman for the band Tonic, talked with PEOPLE in September about the idea of being a dad – a daunting notion for a man whose own father was an abusive schizophrenic who abandoned the family 27 years ago.
