Ticketmaster have issued a number of warnings for fans attending Niall Horan's homecoming concert in Dublin's Olympia Theatre tonight.
Those who purchased tickets for the highly anticipated gig using a credit card have been told the card owner must be present upon arrival.
In cases where multiple tickets were purchased using the same credit card, additional guests will have their IDs cross checked against a purchase list.
In an email sent out last night, concert-goers were told that failure to comply with these rules would result in denied entry:
“Any ticket holder not able to provide the required purchase and identification documents will be denied entry to the venue.
“Any customer found to have exceeded the show’s ticket limit will have their additional transactions cancelled.
Meanwhile, Niall has been posting on social media ahead of tonight's gig, admitting he is both “nervous and excited.”
Ireland , I'm home . Really excited and nervous for tonight!
