X Factor boy group One Direction have said that taking part in the show's tour earlier this year helped them to become more confident and comfortable as a group. The five-piece, who are set to release their debut single later this summer, said they were no "like brothers".
TellyMix were the first to exclusively reveal One Direction last July, just hours after the group first got together at London's Wembley Arena.
18-year-old Zayn, currently dating fellow X Factor 2010 finalist Rebecca Ferguson, said this week: "Time, and performing to thousands of people, has given me confidence.
"We didn't know each other when we were at the show - we were complete strangers."
Speaking to We Love Pop magazine, he added: "Now we feel more comfortable as a group. We're all best friends, or more like brothers."
The group are also excited to releasing their first music, but confessed they were under pressure for it to be good.
"It's a relief because we were looking for a first single for quite a long time. The fans know we've been recording, so there's a bit of pressure," Zayn said.
The group's debut single is expected to be released later this summer, followed by an album in the autumn.
One Direction's winner's song, a cover of 'Forever Young', leaked earlier this year.
