"We're bringing it to North America," the band's Niall Horan told GMA's Robin Roberts. "Tickets go on sale the seventh of December this year. We'll be playing our first show on the first of August in Toronto."

The British superstars' brand new album, "Midnight Memories," has already skyrocketed to No. 1 in almost 100 countries, despite just being released on Monday.

"I think it's such a hard thing to comprehend really," Louis Tomlinson explained of the immediate success of their third album. "We had a bit of a toast and celebration. It's such a hard thing to get your head around. It's a testament to how amazing our fans are, you know?"

Thousands of enthusiastic, screaming fans came out, despite the freezing weather, to watch One Direction perform this morning for the very first time in Central Park "This is so nice," Liam Payne said of the incredible turnout. "We can't believe how many people showed up."

And of course "GMA" couldn't let the pop sensations get away without asking the fans' number one question on Twitter: "Who's still "available" among the bunch?

Harry and Niall wasted no time boldly raising their hands in response to the fact they're single.

Zayn Malik, on the other hand, is completely off the market after his widely announced engagement to Little Mix's Perrie Edwards, though he confirmed no wedding date has been set.
