Justin Timberlake - really nice and approachable, came down in the galley and had a chat with the crew. Really cute also...
Rihanna - had her sunglasses on throughout the flight, did not address any words to anybody. Bit uptight..
Robin Sharma (the author) wrote all flight in his Moleskine, chatted a bit and promised to send me his latest book. Never happened.
Dr Muhammad Yunus the winner of Nobel peace price, extremely nice and kind to everybody.
