Rihanna's collaboration with Calvin Harris, 'We Found Love', has remained at the top of the UK singles chart today as the midweek update was announced. 

The track shot straight in at No.1 last Sunday, October 9, and has managed to beat off competition from this week's new entries from Gym Class Heroes and Matt Cardle.

Travie McCoy's band have teamed up with Maroon 5 for a track called 'Stereo Hearts', which has entered at No.4, and Cardle's new single 'Run For Your Life' charted at No.5 this afternoon. 

'Jar Of Hearts' by Christina Perri has shot up a huge 9 places to No.3 after her headlining performance at London's Water Rats last night (October 11).
