A host of celebrities took to Instagram to send greetings to their fans and followers on New Year's Eve, see how the stars celebrated the occasion here.
Loved-up couple Ronan and Storm Keating rang in the New Year with their family in the Maldives and looked to be having a ball while soaking up the sun.
Meanwhile, actress Aoibhinn Garrihy, who recently announced she's expecting her first baby with husband John Burke, had a cosy celebration in fluffy bathrobes in The Shelbourne Hotel in Dublin.
Glittery dresses were a popular choice for ringing in the New Year in style, with Pippa O'Connor and Rosanna Davison donning eye-catching numbers.
See how the stars celebrate NYE below!

I've never even been to Australia wtf.One of the most intense few days I've gone thru. Big New Year's Eve party cancelled at the last minute and I am left shaking in bed the past two days. I'll leave that with the rest of the bad behind me in 2017 and take with me the many great experiences I've had this year! None greater than the birth of my son Conor Jr. and the continued support of my family, my friends and my dedicated staff through thick and thin. Thank you all and Happy new year to everyone!2018 I may go back to the back pages instead of the front pages again but I have a feeling these journalists now just want me in the obituary pages so we shall see. I will be ready for whatever comes. Be sharp and be fast this year because I am sharper and I am faster.God bless you all and Happy New Year!"
