Age is just a number for Ronnie Wood.

The 68-year-old Rolling Stones guitarist is preparing for fatherhood once again, this time with third wife Sally Wood, 37, a theater producer.

"Sally and Ronnie Wood are delighted to announce that they are expecting twins in June 2016," the band's rep told Mail Online. "Needless to say, they are thrilled and overjoyed with the wonderful news."

Ronnie has four grown children and nine grandchildren from his first two marriages.

He and Sally, who's about three months along in her pregnancy, wed at London's Dorchester Hotel in 2012 after six months of dating and nine years of friendship. Ronnie's old Faces bandmate Rod Stewart served as best man.

This pregnancy is something Sally has longed for. "A baby would be nice. Obviously we've spoken about it quite a lot," she said in a 2014 interview with The Telegraph, reports Mail Online.

"He's up for it. He's got a lot of friends that are older who have younger children and they all say it's fantastic and it keeps you young," Sally added. "I do think that would be wonderful, but I don't know if it will happen. I hope so."
