1D member Niall Horan said of the discovery: “We discovered 5SOS on YouTube last year and we all knew straight away they were very special. We’re so excited to have them on the road with us and we know our fans are going to LOVE what these lads do.”

Lead singer of 5SOC Michael, said of the incredible news: “None of this has sunk in for us; it's surreal to think we will be on the same bill as a band who are on such a world-wide scale."

"And now I look at my calendar in my iPhone and it goes from `doing our thing, doing our thing, four shows at the O2 arena in two days! It's crazy.''

Crazy it might be, but it is definitely happening as the tour kicks off at London's O2 Arena February 23.
