Mick Jagger Is A Great-Grandfather

Jackson, 21, welcomed her first child with her boyfriend, chef Alex Key, 25, reported CBS News. Jackson and Key’s pregnancy was first announced back in September. “She and Alex are thrilled and broke the news to their immediate families last week. Jade was a little taken aback at first, not least because it means she will be a grandmother by the age of 42,” a source told the Daily Mail at the time.

Jackson is the daughter of Jade Jagger, 42, who is now a first-time grandmother. Jade Jagger is actually expecting another child of her own with her husband Adrian Fillary.

Mick Jagger, 70, had Jade Jagger with his ex-wife Bianca Jagger. In total, the rocker is father to seven children – Jade, Karis, Elizabeth, James, Georgia May, Gabriel and Lucas – by four women – Bianca Jagger, actress Marsha Hunt, Jerry Hall and Luciana Gimenez.

Upon learning that he was to become a great-grandfather, Mick Jagger was reportedly more than happy. “Mick is delighted and has no qualms about being a great grandfather,” the Daily Mail insider added. “He’s been joking about becoming a great, great, granddad and still performing!”
