Ronnie Wood has become a grandfather for the eighth time.
The Rolling Stones guitarist's daughter Leah Wood gave birth to her son on May 26.
Proud grandad Ronnie, 66, was the first member of the family to publicly share the news. He tweeted a photo of Rolling Stones baby clothes alongside a message of congratulations for Leah and her husband Jack MacDonald.

Leah, 35, has been married to financier Jack since 2008 and the couple already have a daughter called Maggie.
Otis was born just two days before his big sister's fifth birthday on May 28.
Ronnie has four children. His eldest son Jesse, from his first marriage to Krissy Wood, is now married to Fearne Cotton with whom he has a son Rex - as well as having two older children from a previous relationship.
Leah and her brother Tyrone are Ronnie's children from his second marriage to Jo Wood. He also adopted Jo's son Jaime from a previous marriage. Jaime is the father of three more of Ronnie's grandchildren.
Baby Otis certainly won't be short of third generation rock royalty playmates as he arrived just a week after Ronnie's bandmate Mick Jagger became a great-grandfather following the birth of his granddaughter Assisi's baby girl.
