"I was a bit nervous alright as it's not every day that you strip off in front of 20 people," said the 22-year-old.
"They basically styled me to look a lot older as the storyline is me in an office setting and I'm really stressed and then I go home and have a shower and then I'm all relaxed.
"I wasn't totally naked but I wasn't far off it. I was wearing a g-string and then they gave me stickers to cover my boobs and then they shot it from my chest upwards. It was all done very tastefully but it was definitely weird being half-naked in front of so many strangers.
"We shot it in Kileen Castle in Meath so the setting was amazing. I think it's going out in May so I'm dying to see it."
And the Assets model said she would love to do more TV work after making her first ad for Triton showers.
The petite beauty was letting her hair down over the weekend accompanying boyfriend Luke Fitzgerald to the Leinster Rugby Ball Awards.
Turning heads in a full-length aquamarine Gucci dress, she added how it was her first big night out in a long time -- and her first time attending the bash.
She was seen catching up on all the gossip with her model pals Holly Carpenter and Hazel O'Sullivan (pictured left with Fergus McFadden) as they enjoyed the awards night in the Mansion House.
The model also revealed how she's loving life as a brunette, having ditched her trademark blonde locks for long brown extensions by Ceira Lambert.
"They're actually really easy to maintain and they last about six months so they're brilliant," she said.
She's also looking forward to jetting over to Bordeaux next weekend to cheer on the boys in blue as they take on French team Clermont Auvergne in the semi-final of the Heineken Cup.
