Harry Styles was caught on camera grabbing Niall Horan's crotch at the 2015 Billboard Music Awards on Sunday night, May 17. The incident happened right after One Direction was announced as the winner for Top Touring Artist category.

As the band was called, Niall stood up and moved back to give way to his bandmates out of their row. When he went to hug Harry to celebrate their win, Harry's hand went down and jokingly grabbed his crotch instead. Getting the touch, Niall was laughing while stepping back slightly. On the other hand, Harry headed up to the stage with a smirk on his face. Crotch-grabbing just showed how close they are as bandmates.

One Direction took home two prizes during this awards show. Besides winning Top Touring Artist, the British-based boyband won Top Duo/Group. It was the first awards show the group attended as foursome, after Zayn Malik departed the group earlier this year.

In addition to paying tribute to their fans, the band paid tribute to Zayn in their acceptance speech. Liam Payne said in his short accpetance speech, "This one is for the fans but there is one more person we want to share this with and that's our brother Zayn."

Zayn made a surprising announcement by quitting the group on March 25. He mentioned on One Direction's official Facebook page the reason behind his exit as he wrote, "'I am leaving because I want to be a normal 22-year-old who is able to relax and have some private time out of the spotlight."

The bandmates admitted that they were a little bit angry with his decision but apparently they were able to accept it after some time. "There were certain parts of this job that Zayn loved and certain parts of the job that he didn't. If you don't like your job, you've got to follow your heart sometimes and go where you need to go. There's no argument with that," Liam said on "The Late Late Show with James Corden".
