A little Vine video made the rounds showing Liam looking a bit unhappy, as he turned on a quick smile to snap a pic, frowned again, then resumed a smile for another pic. Bottom line: he didn't look like he was having much fun.
When one fan commented: "i don't blame liam tbh being that famous must be torrid, and at least he's posing for pictures with his fans unlike other celebrities"
Liam responded: "Truth be told I was just a little tired and wanted to make sure everyone was getting a picture I wasn't faking it."
He went on to clear things up, tweeting: "Lots of people saying I was 'faking' smiles with fans yesterday..."
Liam added, "I usually find when ur taking a photo u don't smile until somebody's about to take the photo," noting, "Sorry to disappoint but I don't walk around like this all day... That would hurt!"
