Simon Cowell looks unusually casual in baggy jogging bottoms and grey T-shirt... following Twitter rant over 'grumpy old man'
Taking to Twitter, Simon tweeted 'Just arrived in Miami. The team were great. Eric travelled with us but one really really grumpy man complained. A Lot!
'He asked to be moved. Complained to the staff. And there was a lot of sighing and tutting. The other passengers were amazing.'
