Twins on the way for Rolling Stones' Ronnie Wood, 68

Rolling Stones guitarist Ronnie Wood, 68, is to become a father again as his wife is expecting twins, a spokesman for the British rock band said.

Wood's wife is 37-year-old wife Sally Humphries, who owns a theatre production company.

"Sally and Ronnie Wood are delighted to announce that they are expecting twins in June 2016," said a spokesman for the band.

"Needless to say, they are thrilled and overjoyed with the wonderful news."

The couple dated for six months before getting married at London's Dorchester Hotel in December 2012.

Wood already has four children: Jesse Wood, with his first wife, former model Krissy Wood; daughter Leah and son Tyrone from his second marriage with Jo Wood; and Jamie, Jo's son from a previous marriage who Wood adopted.

He has nine grandchildren.

Wood, who joined the Stones in 1975, is the youngest member of the four-piece band.

The group are due to play a string of stadium dates in South America in February and March on their "America Latina Ole" tour.
