Mick Jagger becomes great grandfather

London, May 20 (IANS) Singer Mick Jagger has become a great grandfather as his granddaughter Assisi, 21, has given birth to a girl.

The Rolling Stones frontman's granddaughter Assisi delivered her first child with boyfriend Alex Key, reports contactmusic.com.

Assisi is the 21-year-old daughter of Jade Jagger, Mick's 42-year-old offspring, who is also expecting a baby boy next month.

"The women in our family just tend to have children young, it runs in the genes," said Assisi.

"I grew up quite quickly and wouldn't have considered having a child if I was doing what my friends are doing at this stage, messing around. I don't drink, I don't smoke and I'm very settled," she added.
