Do Big Time Rush feel used by 1D?

After helping introduce One Direction to the world back in 2012, Big Time Rush's Kendall Schmidt recently admitted how he really felt about the British boy band's booming success. "It sucked for us," he said. "There would be 2,000 girls outside the show singing their songs, even though we were headlining. The only reason we were on tour with them is because we had the same record label and they were using us to promote them." Yikes!
