Mary Byrne, One Direction, and the other stars of 'The X Factor' were reunited to the sound of ear-splitting screams from 10,000 fans in Dublin's O2 last night.
Byrne drew screams and the first standing ovation of the night from the tweens, teens and mums and dads as she belted out the Barry Manilow classic 'Could It Be Magic'.
Wagner preceded her, dressed in a spangled jacket as he warbled his way through a Ricky Martin classic.
The biggest attraction of the night for the teenagers was One Direction, including Mullingar boy Niall Horan. The screams reached fever pitch when the boys left the stage and ran through the crowd.
