One Direction's Liam Payne and Zayn Malik are saying goodbye to their girlfriends Sophia Smith and Perrie Edwards while on their "Where We Are" tour 2014, amid the controversy sparked by the "oral sex" photo that is going viral on Twitter!

One Direction's Liam Payne and his girlfriend Sophia Smith had to say goodbye when Liam Payne jetted off to South America to kick off the One Direction "Where We Are" world tour 2014. Payne has posted a few emotional Twitter posts recently.

Big Payno posted on Twitter: "Had forgotten how lonely hotel rooms are"

Just a day before, he also tweeted: "Drake- doing it wrong. so true," referring to Drake's song about splitting up.

The lyrics read: "When a good thing goes bad / Its not the end of the world / Its just the end of a world / That you have with one girl."

Liam also posted a selfie on Twitter with his face covered by a hat and the caption: "Can't get you off my mind"

Big Payno could be feeling lonely since the One Direction "Where We Are" tour 2014 kicked off on April 25 in Bogota, Colombia. This distance can't be easy on the young lovers: Liam Payne is 20 and his girlfriend Sophia Smith is 24.

Meanwhile, fellow One Direction singer Zayn Malik and his fiancee Perrie Edwards have learned how to deal with the distance during their world tours. Hopefully Zayn can pass on his advice to Liam before it's too late!

"It's gonna be tough but we always make it work," Perrie told Us Weekly about Zayn travelling for much of this year on the One Direction tour. "Lots of texting and talking. Absence makes the heart grow fonder, I guess."

Meanwhile, Liam Payne and Zayn Malik have been caught up in a recent controversy sparked by a scandalous Twitter photo. The photo was posted by a fan and appears to show Liam Payne and Zayn Malik simulating oral sex on stage - however, upon closer inspection it's the angle that is to blame for the racy photo.

According to Unreality TV, one Twitter fan joked: "i actually thought that liam was giving zayn a bl*wjob oops. don't judge! "

Another posted: "this picture looks like miniature liam is giving zayn a bl*wjob "
