Fans are expected to swarm to a special One Direction shop which opens in New York today.
The store, called 1D World, is located in the city's Penn Plaza and will sell the band's merchandise after their profile rocketed in The States this year.
A huge selection of memorabilia is to go on sale including One Direction branded hoodies, onesies, T-shirts, hats, cardboard cut outs and dolls.
Taking to Twitter to voice his excitement ahead of the grand opening, band member Liam Payne wrote: “Guys just saw the pics from the #1DWorld that opens tomorrow at 9am in NYC!!!! Looooks amazingggg! Go check it out If ur around 2 Penn Plaza. (sic)”
Fellow singer Louis Tomlinson added: “#1DWorld opens in New York tomorrow! Go and have a look!”
Meanwhile, Harry Styles may have left shop bosses shaken after threatening to change his image which would make his doll outdated.
The star allegedly offered to shave off his trademark curls in a bid to raise money for charity.
During an appearance on BBC fund raising show Children In Need on Friday night, host Fearne Cotton said: “So I've heard that you, Harry, will shave your head for Children In Need!”
Harry was left flabbergasted and lost for words prompting Louis to join in, exclaiming: “He did say that, I heard him say that!”
Put on the spot, Harry mumbled: “Sure, go for it if you want.”
And while the singer seemed nervous about the potential haircut, he soon recovered and thanked BBC bosses for inviting them to perform on the charity show.
He tweeted: “Thank you so much to @BBCCiN for having us. It's such a great cause so please donate if you can. .xx (sic)”
