RTÉ's Evanne Ní Chuilin managed to make Ireland's golden rowers blush when she got them to explain why they have all grown moustaches.

The lightweight pair of Mark O'Donovan and Shane O'Driscoll and lightweight sculler Paul O'Donovan all picked up gold medals at the World Rowing Championships in Florida.

The trio are all sporting moustaches on their top lips - not something you see very often amongst elite sportsmen these days.

Ní Chuilin asked them to explain their new growths and even managed to make O'Driscoll blush when the camera zoomed in on his new facial hair.

"We started in Banyoles in Spain on a training camp," said Mark O'Donovan, who explained that the trend was started by the injured Gary O'Donovan, who was unable to partner his brother Paul in the lightweight double sculls in Florida.

"Holiday Joe, AKA Gary O'Donovan started growing one as well, but he ended up shaving it off because he was worried about his nightlife. Holiday No 'Tasche Joe - he let the lads down so it's just the three musketeers now!"

Gary O'Donovan added: "We had nothing more to do that watch them grow to entertain ourselves."

Ireland could yet add another medal to their tally this weekend, with Sanita Puspure going in the women's single sculls final on Sunday.

Ireland's golden boys will all be out supporting her.

"She was in between the two favourites in a very tough (semi-final) race so that was good for her. We'll be back out supporting her, without question. With the flags - don't worry about that," said Gary O'Donovan.

Live coverage of the World Rowing Championships will be broadcast on RTÉ2 on Saturday and Sunday. Coverage Saturday at 4.30 and Sunday at 3.30 with a highlights package at 8.0pm on Sunday
