The Dublin woman had also just finished her Leaving Certificate exams making last night a well-deserved celebration.
Her friends took a video of Harry Style's moving birthday message and Alex's emotional reaction.
Alex told Dublin Live that she never thought the star would actually see her sign having only arrived at the stadium a few hours before the gig started.
She said: "I was literally in shock. I couldn't believe it. I brought the sign not thinking he would actually see it.
"When he saw it I couldn't believe it was happening .
"I literally got there at like 4pm and we went in by 4:30pm.
"We just got lucky. We got right up at the front by the barrier.
"It was kind of just a joke. I didn't actually think he was going to see it and sing it.
"I was honestly just shocked. I couldn't believe that it was happening in the moment. Harry was just looking at me.
"I was literally trying so hard not to cry. It was such a good feeling that everyone joined in. It was just amazing."
