Before flying to America to take the stage with his buddies, the crooning cutie was noticeably absent from the group's appearance on Today Monday morning to promote the release of their new album Four at Universal Orlando Resort—and everyone wanted to know why.
Matt Lauer had his own theories (which didn't sit well with the ill singer) and Liam Payne explained that his pal had a "tummy bug," but Louis Tomlinson told E! News what was really going on...oh, and just a warning: TMI ALERT.
"He's got a poo problem," Louis told us. "And that's the truth and he's really not gonna like me saying that."
LOL! Well, at least that seems to be under control now.
