The group, which includes Max George, Jay McGuiness and Tom Parker, certainly made their presence known when they met fans at the HMV Dundrum store on Tuesday afternoon (19 November).
The boys were greeted with a cacophony of deafening screams and rather tearful fans when they made their appearance at the shop after jetting into Ireland earlier that day.
No doubt it was a particularly special experience for Siva who was born and raised in the Irish capital.
He tweeted afterwards: "What an amazing turn out today at our signing in my home city Dublin!! Thanks to all of you that came to see us."
Siva wasn't the only one overwhelmed by the response as Max tweeted: "Our Irish fans are soooo nice!!... Missed you guys."
The Wanted were at HMV to sign their new album Word Of Mouth, which features a string of fab singles including 'Show Me Love (America)' and 'Chasing The Sun'.
Store owners anticipated a massive turnout (and they were right!) so security was beefed up ahead of the event and fans needed a wristband to get through the doors.
(Any fans who didn't get a wristband will get the chance to see the guys next year when they bring their 'Word Of Mouth World Tour' to Dublin in March.)
The Wanted stayed overnight in Ireland after the signing as they're performing at tonight's star-studded Childline Concert at the O2 in Dublin.
They'll share the bill with acts including Little Mix, Boyzone, Conor Maynard and Shane Filan. All the acts have given their services free of charge meaning the full proceeds from the event will go to charity.
Good looking, love their fans and generous? We think our The Wanted crush just got a bit bigger…
