Eurovision fans were left shocked after a member of the audience burst on stage and grabbed SuRie’s microphone.
Graham said: “I’m not sure what they’re going to do now!”
Visibly shaken, SuRie was given another microphone and defiantly completed her performance.
Graham added: “Well, the utmost respect for SuRie and a suitably euphoric response from the crowd here in the arena.
“I mean, she was doing a brilliant job anyway!”
Those tuning into Eurovision were quick to comment on the incident with many baffled by what had taken place.
One viewer shared on Twitter: “OMFG huge respect to @surieofficial for carrying the song on after someone got her mic #EUROVISION #Eurovision2018 #GBR.”
Another added: “#Eurovision Surie smashed it but what just happened?? She’s amazing #uk #Eurovision2018.”
A third begged: “Come on @Eurovision the United Kingdon #uk needs to sing again! Otherwise very unfair. #eurovision #Eurovision2018.”
“#Eurovision2018 well done #UK with the interruption,” someone else continued.
Graham later added: “What a dramatic turn of events for SuRie and the UK – but she turned it to her advantage and carried on.
“I can’t stress enough what a brilliant job she did. It must have been terrifying in that moment.”
Eurovision is available to watch on BBC One now.
