Former Rose of Tralee and lecturer Aoibhinn Ni Shuilleabhain has revealed she has campaigned for 'Yes' votes on behalf of her students.
The UCD lecturer, who works in the school of mathematical sciences, said she feels strongly about the campaign because she wants all of her students to feel equal whether they are in the classroom or not.
The broadcaster (31) has been canvassing for 'Yes' votes in both Dublin and her home county of Mayo.
"I don't have anyone in my immediate family who is gay but I have an awful lot of really good friends who are gay, and I suppose I've seen the difficulties in coming out, and also in their interactions in everyday life," she told the Herald.
"As a former teacher and an educator, it's something I'm quite wary of.
"All of my students need to feel that they are equal in whatever classroom they're in and they also need to feel that they're equal members of society.
"We have a very open society here in Ireland I think that this is one of the last civil rights that we have to deal with," she added.
Aoibhinn urged voters to read up on the referendum before making the final decision on their vote.
"It's important that people at least consider voting 'Yes'," she said.
"It's about making an informed decision and there's a lot out there that isn't necessarily the right information. People need to read up on the referendum and find out what it's actually about."
