Ronan's wife expecting baby

Yvonne and Ronan Keating: They already have a baby son

Boyzone frontman Ronan Keating's wife Yvonne is expecting the couple's second child, the singer has announced.

The news comes two days before Keating, 23, is expected to shoot to number one in the UK album chart with his debut solo LP, Ronan.

He said: "My wife and I are absolutely thrilled we are going to have a little brother or sister for baby Jack."

Yvonne is expecting the baby in February.

Keating's album is set to go to number one on Sunday

Jack was born 12 days overdue in March 1999 at Mount Carmel Hospital in Keating's home city of Dublin.

Keating married Yvonne, a 26-year-old model, in 1998 in the Caribbean.

His last single, Life Is A Rollercoaster, went straight to number one last month, but only stayed at the top for a week after a record company error meant that one version of the record was declared ineligible for the chart.

While he was promoting the single, police swooped on MTV's UK studios in north London after a death threat prompted fears for his safety during a live broadcast.

He was forced to swap studios because of the threat, which was received on his website.
