The actor ditched his clothes during an appearance on The Ellen DeGeneres show, where he was put in a ‘splash tank’ as part of the host’s month-long Breast Cancer Research fundraiser.
On his way to the tank, a confident O’Connell jumped into the audience and danced around for his female fans, who slapped his behind as he strutted through.
DeGeneres called on O’Connell’s wife Rebecca Romijn to throw baseballs at a bullseye in a bid to to release a wave of water on the star’s head, but the actress missed after three attempts.
DeGeneres’ partner Portia De Rossi, who stars opposite O’Connell in upcoming TV special Mockingbird Lane, then lobbed two balls at the target, striking the marker and releasing the water onto his head.
O’Connell is the latest star to get wet for charity – Liam Neeson stripped off for the challenge earlier this month (Oct12), and Madonna roped her son Rocco into taking part in the stunt earlier this week (begs22Oct12).
Young Rocco’s water challenge will air on the show next week (begs29Oct120)
