If he can't get no satisfaction, maybe that's because Mick Jagger is a great-grandpa.
The baby, whose name was not announced, is the first child for the 21-year-old Jackson and her boyfriend, 25-year-old chef Alex Key
The baby's birth makes Jackson's mother, Jade Jagger, a first-time grandmother. Jade, 42, is expecting a baby of her own later this month with husband Adrian Fillary.
Jade is Sir Mick's daughter by ex-wife Bianca Jagger. The Rolling Stones frontman has seven children in all.
The Stones are due to resume their 14 On Fire tour on May 26 in Oslo, Norway. The tour was cut short in March following the suicide of Jagger's longtime girlfriend, fashion designer L'Wren Scott.
