Ronan Keating, the Irish singer and songwriter, turns 35 on Saturday.

Keating debuted in 1994, as the lead singer for boy band Boyzone. His records, both with the group and as a solo artist, have sold more than 22 million copies worldwide. His song, "When You Say Nothing At All", has topped the charts in several countries.

Keating is married to model Yvonne Connolly and has three children.

He also runs the Marie Keating Foundation, an organization in his mother's name, which works to promote awareness about breast cancer. Keating has also served as a Goodwill Ambassador for the United Nation's Food and Agricultural Organisation and received the Special Achievement Award from Cancer Research UK, in 2009.

Meanwhile, Keating will be joining Keith Duffy, Mikey Graham and Shane Lynch in 2013, to celebrate the 20th anniversary of Boyzone as a group. On the eve of his birthday Keating tweeted: "My last day at 34. Tomorrow 35."
