The Westlife singer, 33, was clearly thrilled to be landing back in the country of his birth after spending the past month in Australia filming the ITV show - which he went on to win.
Before boarding the flight into Dublin airport, he shared his thoughts with his Twitter followers, saying: "Just about to take off for Ireland. Really looking forward to a cup of Lyons tea. Exciting to be going back to my home country."
Although he was pleased to be home, Kian - who is also a coach on the Irish version of The Voice - couldn't help reminiscing about his time in the jungle with the likes of Alfonso Ribeiro, Joey Essex, Lucy Pargeter and David Emanuel.
Posting a group shot of the celebrity contestants and their families, he wrote the message: "Missing my jungle family. What a crazy adventure. Love this lot!:-)"
He added: "Missing my bro @alfonso_ribeiro hope all is well back in la la land bro. Good to be back I'm sure."
The Sligo-born lad, who is married to singer and actress Jodi Albert and dad to son Koa, also told his Twitter fans that he couldn't stop eating after weeks spent eating beans and rice in camp.
He joked: "After loosing all the weight (Nearly a stone) if I keep eating the way I do it will be back on before Christmas never mind after Christmas!"
