Rolling Stones star Ronnie Wood is set to become a grandfather again - his son Jesse's girlfriend, British TV and radio personality Fearne Cotton, is pregnant.

The BBC presenter announced the baby news in a post on her website on Wednesday.

Cotton, 30, wrote, "Jesse and I are very happy to announce we are having a baby. We are over the moon, morning sickness aside (me, not Jess) and looking forward to the little Cotton Woods arrival."

Wood last became a grandfather in 2009 when his daughter Leah gave birth to a baby girl.

Jesse has two sons from his first marriage to Krissy Findlay, while the rocker's stepson, Jaime, also has two kids.
