AND they say she doesn't know how to have a good time.
Glamorous presenter Aoibhinn Ni Shuilleabhain (right) has said she prefers working on maths equations than jet-setting around the world for her RTE show Getaways.
"I like travelling but maths is what I'm passionate about," the 30-year-old told the Diary.
"Telling people where to go on holiday is important but not as important as maths. I prefer teaching and studying maths – it's more rewarding."
The presenter, who recently moved into a €1.2m Dublin pad with her other half Ryan Tubridy, is on a mission to make maths cool.
She believes Professor Brian Cox and Dara O'Briain have been instrumental in boosting the popularity of science.
And the former Rose of Tralee says maths can follow suit.
"I think people like Brian Cox, Chris Hadfield and Dara O'Briain have made science cool," she explained.
"I think the same can be done with maths. People should be proud of their interest in the subject and their knowledge of it.
"They should own that talent instead of feeling embarrassed by it.
"Being good with numbers is a great skill set to have," she added.
Aoibhinn was talking at the launch of the 2014 Discover Primary Science and Maths' awards of science and maths excellence.
"I think it's a great initiative and encourages kids to be confident in their abilities. It's the 10 year anniversary so I'm delighted to be involved."
