Congratulations to 73-year old Rolling Stone founding band member Mick Jagger on the birth of his 8th child with his ballerina girlfriend Melanie Hamrick.

“Melanie Hamrick and Mick Jagger’s son was born today in New York and they are both delighted,” a rep for Jagger told New York Post‘s society column “Page Six” on December 8. “Mick was at the hospital for the arrival.”

The rep added that both Hamrick, who is more than 40 years Jagger’s junior, and the baby are “doing well,” and noted, “We request that the media respect their privacy at this time.”

The couple started dating in 2014 after Jagger’s partner of 13 years L’Wren Scott committed suicide in 2014.

Jagger is also a grandfather. He shares children with exes Marsha Hunt, Bianca Jagger, Jerry Hall and Luciana Gimenez Morad.

His children, Georgia, James, Jade, Elizabeth, Lucas, Karis and Gabriel, range in age from 17 to 45. The baby has a 45-year old half sibling in Kari! Wowza!

Jagger is also a granddad to five children and became a great-granddad in May 2014, when his granddaughter Assisi, daughter of Jade Jagger, gave birth to a baby girl.
