Los Angeles, Singer Mick Jagger has told his The Rolling Stones bandmate Ronnie Wood that he will be a nanny to his twin daughters next year. Wood will become a father for the fifth time when his wife Sally Humphreys gives birth this summer, and the guitarist has started calling his friend "Nanny Mick" after Jagger's offer, reports mirror.co.uk. “The Rolling Stones are all thrilled. Keith loves kids, so he's excited, and Mick keeps telling me to give him a year and then he'll be our nanny. So now we're calling him Nanny Mick,” Wood told HELLO! magazine. “Everyone is thrilled for me. 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 and Keith's girls (Theodora and Alexandra) and Charlie's 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,” he added.
