Singer Ronan Keating was a guest star on Saturday Night Takeaway, and he was on great form as he belted out one of his biggest solo hits Rollercoaster.
Ronan, 43, revealed last week that he was self-isolating after over Coronavirus fears.
The Boyzone star, who presents the Magic Radio Breakfast Show, recently returned to the UK after performing in Singapore.
After his trip the hitmaker took the precaution of working remotely from home.
Speaking on the show Ronan said: "We have to be cautious, we have to be clever about it and it makes total sense. I'm feeling fine."
Magic Radio said that with many staff sharing equipment within its studios the decision was made to take the extra measure.
Ronan, who had displayed no symptoms of the virus, was able to interact remotely with his co-host Harriet Scott as usual and Magic reassured that unless government guidance changed he would return to the studios next week.
Fans were thrilled to see the pop star on the ITV entertainment show hosted by Ant and Dec.
The duo vowed that the show must go on and promised to deliver some much-needed smiles with tonight's show - and they delivered with Ronan.
Viewers took to Twitter to remark that the youthful star, who shot to fame with the boyband Boyzone in 1994, doesn't seem to have aged at all.
"Ronan Keating hasn't aged a day," tweeted one.
"Has Ronan Keating even aged?" asked another.
"Ronan Keating has not aged at all," gushed another fan.
And another said: "Ronan Keating is looking good these days isn't he?"
Ronan is expecting a baby girl with his wife of five years Storm.
He is father to Jack, 20, Missy, 18, and Ali, 14 from his first marriage and he has a two-year-old son Cooper with Storm.
