Mick Jagger Becomes Great-Grandfather

Sir Mick Jagger , the 70-year-old frontman for the Rolling Stones, has become a great-grandfather.

Jagger achieved the new status over the weekend when his granddaughter Assisi Jackson, 21, gave birth to a baby girl , the Daily Mail reported.

According to CBS News, the infant is the first child for Jackson and her boyfriend, 25-year-old chef Alex Key. The baby's name has not been released .

The rock legend, who has been performing since 1962 , has seven children with four women, and four grandchildren. Jade Jagger, Mick's daughter by ex-wife Bianca Jagger, is the baby's 42-year-old grandmother. The former model and socialite is expected to give birth to her third child in the next few weeks.

"The women in our family just tend to have children young , it runs in the genes," Jackson told Hello! magazine.

This has been a tumultuous year for the singer. Jagger's girlfriend , 49-year-old fashion designer L'Wren Scott , committed suicide in March. The couple had been together since 2001.

"I am still struggling to understand how my lover and best friend could end her life in this tragic way," Jagger wrote on Facebook . "We spent many wonderful years together and had made a great life for ourselves."

The loss prompted the Rolling Stones to reschedule its Australian and New Zealand concert dates. The "14 On Fire" tour is set to resume on May 26 in Oslo.

Jagger was inducted into the Rock and Roll Hall of Fame with the Rolling Stones in 1989. The British singer was also knighted for his services to music in 2003.
