Sir Mick Jagger has become a father again at the age of 73. The Rolling Stones frontman welcomed his eighth child with American ballerina Melanie Hamrick on Thursday (8 December) in New York, his publicist confirmed.

According to a statement, the proud parents are "both delighted" about the new addition. "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," the rep said. The little boy's name has yet to be released.

The couple started dating following the suicide of Jagger's partner of 13 years L'Wren Scott in 2014. News of Hamrick's pregnancy broke back in July with an insider telling The Sun that the couple were both "surprised and happy" with the news.

The source added: "This is great news. It will be Mick's eighth child and nothing fazes him. He's been incredibly supportive."

Jagger is already father to Karis Hunt, 46, Jade, 45, Elizabeth, 32, James, 31, Georgia, 24, and Gabriel, 18 and Lucas, 17 from previous relationships.

The new arrival will also be young than his five grandchildren and great-granddaughter. It also means that the legendary rocker has joined the ranks of septuagenarian dads including Robert DeNiro and Rod Stewart.
