I used to be a goth, says Aoibhinn as she casts off safe style in new sizzling photoshoot

SELF-confessed "geek" Aoibhinn ni Shuilleabhain has ditched her 'schoolmarm' look for a sizzling new photo shoot.

The maths teacher girlfriend of Ryan Tubridy admits her nomal style is "pretty boring" but these new pictures show she's anything but dull.

Aoibhinn (29), who has five brothers, explained that she was never a "girly girl" growing up in Mayo.

"It's changed so much. When I was a teenager, I was a real rock chick, a goth. I hung out at Metallica concerts and had blue hair for a while, then dyed it fire-engine red. Now I'm a big fan of vintage fashion. I love 50s-style dresses," she said.

"I'd be out in the countryside and going for big, long walks, if that qualifies. But now I love wearing high heels and getting all dressed up. It depends on the occasion, I guess."

She told Stellar magazine how she's a total geek at heart but laughed how it's "fashionable to be one" at the moment. "I love science and reading about it and keeping up to date with all the research so if that qualifies me as a geek, I have no problem being called that," she continued.

The globe-trotting beauty is currently studying for her PhD in Maths Education in Trinity and was in Portugal recently for an educational conference. But she's also planning a big trip to Argentina this August -- but there's no word yet if her RTE boyfriend will be joining her over there. Going to the south American country is part of a life-long dream of hers to have travelled the world before she reaches a milestone birthday.

"I'm really looking forward to that. It's not a competition but it's my 30th country and I think it's great to have hit 30 countries by the time I'm 30," she explained.

"Lots of my friends are hitting 30 and it seems to be just an excuse for a good party. The only thing I want to do is visit the six continents by the time I'm 30."

The former Rose of Tralee contestant is also starting a new TV show on RTE entitled The Science Squad. "I'm so thrilled because I've wanted to present a science show for so long and I think it's really important to promote the subjects of maths and science.

"Not just because they're so relevant at the moment but because they're just so interesting. You've got great scope to be creative and imaginative with them," she said.
