A remix of Katy Perry's new single 'The One That Got Away' featuring B.o.B has appeared online.

The track sees the rapper kick off the song with a new verse, before appearing again later during the song.

It marks the third time Katy has enlisted a hip-hop star to remix one of the songs from her latest album 'Teenage Dream' – Missy Elliot previously featured on 'Last Friday Night' and Kanye West starred on a remix of 'E.T'.

'The One That Got Away' is the sixth single to be taken from the singer's second album.

The star is currently attempting to break the record for the most number ones from one record on the US Billboard Hot 100. She is currently joint record-holder with Michael Jackson.

Meanwhile, Katy condluded her 'California Dreams' world tour in the US earlier this month.

It has been reported that Katy and her husband Russell Brand are planning to return to the UK to spend Christmas together.
