London: Rolling Stones guitarist Ronnie Wood has become a father again at 68 after his wife, Sally Humphreys, gave birth to twin girls.

Wood’s publicist Karen McNamara said in a statement on Tuesday that the couple “are delighted to announce the birth” of Gracie Jane, who weighed 6 pounds (2.7 kilograms), and Alice Rose, who weighed 5.7 pounds (2.58 kilograms).

The statement said the babies arrived Monday at 10.30pm, “and all are doing brilliantly. The babies are perfect”.

The twins are the fifth and sixth children for Wood, who turns 69 on Wednesday, and the first for 38-year-old Humphreys, who married the rocker in 2012.

In February, Humphreys flew home from a Rolling Stones tour of Brazil to avoid exposure to the Zika virus, which has been linked to microcephaly in babies.

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 whom Wood adopted.

He has nine grand-children.

Wood and his wife, who owns a theatre production company, dated for six months before getting married in 2012. Rocker Rod Stewart served as Wood’s best man.

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