Rihanna has reportedly put to bed rumours of a possible reconciliation with former lover Chris Brown by spending the night with reality star Robert Kardashian.

According to celebrity website MediaTakeOut.com, the singer rounded off her 24th birthday celebrations by hooking up with Kim Kardashian's younger brother.

A source told the site that the unlikely pair got together after a heavy makeout session at London nightclub Mahiki. The We Found Love singer was sptted with love bites on her neck.

The insider claimed that the Bajan beauty and Kardashian were "all over each other" at the club and were later spotted leaving together.

Rihanna managed to surprise fans when she released two new tracks on her birthday on 20 February, which had been produced in collaboration with Brown.
