U2 sold out their concert at Croke Park last night, with over 80,000 fans attending.
Two of these fans were Aaron Maher and his girlfriend Fiona Robertson.
Little did Fiona know, Aaron had something up his sleeve.
Just as U2 began to play ‘With or Without You’, Aaron popped the question.
Although the memory of seeing your favourite band live never fades, Fiona will definitely never forget the moment Aaron got down on one knee.
Check out her reaction – you may need some tissues!
