Sonny Bono's daughter has given birth to her first child - on what would have been the late singer's 77th birthday.
Chianna Bono, the I Got You Babe hitmaker's 21-year-old daughter with Republican U.S. congresswoman Mary Bono MACk, delivered little Sonny William Hrabe on Thursday (16Feb12).
Chianna's half-brother Chaz Bono, whose mum is pop star Cher, confirmed the news on Twitter.com.
Chaz wrote, "Happy to share that my nephew, Sonny William Hrabe, was born today, on his granddad's b day (birthday). Congrats to all the Bonos, MACks, & Hrabes."
Sonny Bono died in a skiing accident in 1998 at the age of 62.
