Keith’s eldest daughter Dandelion is eight months pregnant with her first child!

Infamous rock legend Keith Richards does more diaper-changing than drug-taking these days — the 67-year-old is not only a father of four, but he’ll be a grandfather of four when daughter Dandelion gives birth next month. And friends say he couldn’t be happier!

The 39-year-old — who goes by her middle name Angela — is Keith’s daughter with former girlfriend Anita Pallenberg. Her elder brother is Keith’s son Marlon, 42, who has three kids of his own.

Aside from her hands-on rock royalty dad, there’ll be plenty of aunts and uncles to help out — Angela has two younger half-sisters from Keith’s marriage to current wife Patti Hansen; Theodora, 26 and Alexandra 25.
