B.O.B gave passengers on a recent flight to Australia a free performance.

The rapper, who will be performing at The Grammy Awards this weekend, surprised passengers on a flight to Australia when he sang his number one hit 'Aeroplanes' over the speaker system, reports The Sun.

B.O.B is currently at the top of the UK charts with Jessie J on her new single 'PriceTag'.

Meanwhile, Rihanna will perform with Drake, while Cee Lo Green is due to collaborate with Hollywood actress Gwyneth Paltrow.
