The singer sounded a bit miserable last night

Liam Payne left One Direction fans a little worried last night with an emotional Tweet.

The singer, 20, had earlier flown to Bogot√°, Colombia for the first night of 1D‘s Where We Are stadium world tour – which starts tonight – but seemed a little down about the situation.

‘Had forgotten how lonely hotel rooms are,’ wrote Liam.

Liam‘s message came after he’d Tweeted that ‘nobody really knows me’ while ‘a bit wasted’ over Easter weekend but he seemed to have cheered up by Tuesday.

After renting a Lamborghini in LA, he told followers: ‘Literally had one of the best days ever, I just wanna say thanks to everyone for getting me here… being in this position is the best.’

Directioners have been sending Liam supportive messages since his latest comment.

‘stop bringing yourself down like this ! You’re a good and smart person, hang in there ,’ Tweeted one.

Another wrote: ‘:((( this made me sad babe :(,’ while a cheeky devotee said: ‘go sleep with niall.’
