Stars on both sides weigh in on vote
Several celebrities have weighed in on the referendum.
Gladiator star Russell Crowe retweeted a video posted by Saoirse Long, sharing her story of travelling to the UK for an abortion.
The actor shared the video with the caption: "I have two beautiful sons. I wasn't lucky enough to have a daughter. If I had, I'd wish her to have courage like yours."
Former One Directioner and now solo star Niall Horan tweeted: "Cmon Ireland! This is your day to make another great decision. Please do right by the great women of our nation."
Former footballer and BBC broadcaster Gary Lineker has also weighed in, tweeting: "Here's hoping Ireland do the right thing by their women today. #Repealthe8th."
Ireland internatioanl rugby star Cian Healy also weighed in on the issue.
"As a man, adopted in Ireland 30 years ago where the 8th possibly protected me, I (and my family) are supporting the YES vote. We must make sure the women of Eire are protected and have a choice in their lives," he said.
Meanwhile, on the No side, Love/Hate star John Connors tweeted: "Just voted for babies who have no vote. I hope the Irish people show their humanity, compassion and hearts today. When you are in that polling booth there will be just you in there. No repealers to bully you. Vote no."
Jim Corr, who has backed a No vote, stated: "Thank you everyone for putting your hearts and souls into this. You are the most amazing of people."
