Former US President George W Bush has braved the ice bucket challenge after being nominated by Northern Ireland golfer Rory McIlroy.
The four-time Major winner and his fellow Nike ambassador Tiger Woods took part in the latest craze before the 43rd President of the United States took on the charity challenge.
The Co Down man also nominated Manchester United captain Wayne Rooney and American actress Meghan Markle from hit legal drama Suits to chuck cold water over themselves and post the evidence online.
Bush is the latest well-known figure to consent to the quirky challenge to raise funds for the Amyotrophic Lateral Sclerosis (ALS) Association.
In a video posted on the internet yesterday, he said: "I do not think it's presidential for me to be splashed with ice water, so I'm simply going to write you a cheque".
The his wife, Lauren Bush, 'surprised' him by emptying a bucket of ice water over his head in a clip that has gone viral.
"That cheque is for me," she said.
"I don't want to ruin my hairstyle."
Current US President Barack Obama is not likely to take on the challenge.
A spokesperson said: "We've had other things on our agenda."
