Ronan Keating and his wife Storm are expecting their first child together.

The former Boyzone singer, 39, is already father to Jack, 17, Missy, 15, and Ali, 11, from his marriage to Yvonne Connolly and has previously spoken about his desire to expand his family.

Storm, 35, announced the news on her blog alongside a picture of the family drinking mulled wine.

She wrote: "On the 17th August in 2010, my husband and I became friends.

"On the same day five years later we became husband and wife. We're now very excited to announce that a year later (and again to the exact date) we became parents-to-be!!

"And so THAT'S why I passed on the mulled wine.

"Words cannot describe how overwhelmed with happiness we are. We feel so blessed to be adding another little Keating to the family and this news is like all of our Christmas wishes coming true.

"This Christmas we'll just be asking Santa to keep our baby safe and to spread some extra happiness and joy to you and all your families also."

The couple got married at Archerfield House in East Lothian, Scotland, on August 17 2015, with Keating's children playing best man and bridesmaids.
