George Michael played Dublin's O2 Arena last night, following the cancellation of a couple of the Royal Albert Hall legs of his mammoth tour.
The former Wham! singer was forced to announce last Wednesday (26 October) that he could not perform due to illness.
However, he made a comeback at the same venue on Saturday and earned himself a celebrity superfan in the process.
Pop superstar Justin Timberlake was in the audience for the show and was totally wowed by the singer's showing.
"It was beautiful," the N*Sync man said in an interview with BBC Newsbeat. "It felt like a night I would remember forever.
Timberlake added: "I felt lucky to see him there in that venue. It was very intimate and he was so forthcoming. I really enjoyed it - I thought it was a spectacular show."
