The singers are good friends

Cheryl Cole and Rihanna have been enjoying a flirty conversation on Twitter.

Rihanna, 24, told her followers that she’d been asked about ‘perving’ over Cheryl, 28, and fellow Brit singer Adele, 23 – with Chezza responding that she often does the same thing.

‘Had an interview for Esquire UK lastnight! They always get me pervin’ on @CherylCole and Adele #girlcrush,’ Tweets Rihanna.

Cheryl replies: ‘No problem.. @rihanna I’m always pervin on you anyway.. Minus interviewer.. Lmao #girlcrush #pervin4thefunofit.’

Cheryl first met Rihanna when she presented her with the Best International Female gong at The Brit Awards last year.

In December, she and Girls Aloud band mate Nicola Roberts watched the singer perform at London’s O2 Arena from a private box.

Just left last #Loud concert. Amazing!! To put on 98 of the same shows like that and give your all takes something special,’ Cheryl told her Twitter followers.

‘Congratulations on completing your tour @rihanna Have an amazing Christmas, well deserved break and another amazing year! #illdrinktothat X.’
