Ronan Keating to swim Irish sea

London: Irish pop star Ronan Keating is set to make a splash for a good cause by swimming the Irish sea to raise money for cancer charities.

The "Boyzone" singer is hoping to set a new Guinness World Record for open water swimming when he takes part in the relay with a 10-member team which will also include business tycoon Sir Richard Branson, reports

And Keating admits he`s nervous about braving the 90-km stretch from Dublin, Ireland to Holyhead in Wales.

"I`m not a strong swimmer so it`s going to be a real challenge for me," he said.

The group aims to raise $1.6 million for Cancer Research Britain and the Marie Keating Foundation when they tackle the feat in September.
