Congratulations are in order for Mick Jagger and his girlfriend, American ballerina Melanie Hamrick.

The two welcomed a baby boy on Thursday, their first child together. The 73-year-old Rolling Stones frontman is already a father to daughters Karis, Georgia May, Jude, and Elizabeth, as well as sons James, Lucas, and Gabriel, from previous relationships.

"Melanie Hamrick and Mick Jagger's son was born today in New York and they are both delighted," a rep for Jagger tells ET. "Mick was at the hospital for the arrival. Mother and baby are doing well and we request that the media respect their privacy at this time."

ET spoke to Jagger at the opening of a Rolling Stone exhibit in NYC in November, when he called becoming a dad at 73 "very nice."

In addition to his eight children, the legendary rocker also has five grandchildren and one great-grandchild, whom he welcomed in May 2014.
