Even though One Direction has been at the top of their game for a couple years now, Liam Payne still can't believe just how many fans he and the boys have. 

The 20-year-old took to Twitter to show a picture of thousands of fans who came to their hotel in Lima, Peru as their "Where We Are" world tour kicked off.

"I will never understand, and you will never understand what this does to somebody ...why? no one could deserve this," he tweeted.

Following the first show in Colombia, Liam wrote, "The greatest experience of my life."

And after playing in Lima, he added, "Honestly you guys are gunna set me off again Lima that was an overwhelming experience something I'll remember forever... It's so crazy I feel like I haven't done enough to deserve that kind of appreciation gunna spend my day in a state of shock love you guys."

On April 25, the five men performed to an estimated 40,000 screaming fans at the El Campin stadium.

Earlier in the day, the boys did a big press conference for South American media, where they said that they were nervous but excited.

Niall Horan, 21, said, "I’m a bit nervous at the minute because it’s our first show of the tour. Because we’ve known about this tour for like a year. We’ve been really excited, so it’s all going to come out tonight. We’re going to have a good time. We rehearsed in the venue yesterday and you can feel the adrenaline running through."

The tour opens in Europe in Croke Park, Ireland on May 23, before landing in London's Wembley Stadium on June 6.
