Ronnie Wood and wife Sally 'welcome twin girls'

Ronnie Wood's theatre producer wife Sally Humphreys reportedly gave birth to twin baby girls on Monday (30May16).

British newspaper The Sun reported the arrival of the couples' first children together, joining Ronnie's other kids from previous relationships. The Rolling Stones rocker has four adult children from his previous two marriages to the late Krissy Findlay and Jo Wood.

Sally, who is 30 years his junior, wed Ronnie in 2012 after a six month whirlwind romance.

Ronnie announced the surprise news he was expecting twins with the 38-year-old in December (15). The couple had apparently been trying to conceive for some time.

In anticipation of the twins arrival, Ronnie posted a tweet on Monday (30May) titled: "Waiting #38weeks+".

Earlier this year he revealed the band's excitement over the arrival of his children in an interview with HELLO! magazine.

"The Rolling Stones are all thrilled. Keith (Richards) loves kids, so he's excited, and Mick (Jagger) keeps telling me to give him a year and then he'll be our nanny so now we're calling him 'Nanny Mick'," he smiled.

"The Stones are one big family. It's all about the kids. In this tour, everyone's been there: (Mick's children) Jade, Karis, James, Lizzy, Gabriel, Lucas and Georgia May; Patti (Hansen) and Keith's girls (Theodora and Alexandra) and Charlie's (Watts) granddaughter Charlotte.

"My girls will be two more added into the mix. I hope my girls will be coming on tour with me for years to come."

Ronnie, who is worth an estimated £35 million ($51 million), had his first child Jesse, 39, with first wife Krissy, who passed away in 2005. He wed model Jo, 61, in 1985, divorcing in 2011. As well as adopting her son Jamie, 41, from a previous marriage, they also had daughter Leah, 37, and Tyrone, 32, together.
