Rihanna and Chris Brown share secret tweets

Rihanna and Chris Brown have been secretly tweeting each other.

The 'Yeah3x' singer was caught out after he sent Riri a public tweet which was meant to be private.

Chris quickly deleted the message but one of his followers took a screen grab of the exchange, reports The Metro.

'@Rihanna you got that pic I sent,' he wrote.

The tweet comes after Riri recently added Chris to the list of people she follows on her Twitter page.

The move sparked fury among her fans which led her to defend her actions, tweeting: 'It's Twitter, not the altar calm down.'

Chris was sentenced to five years probation and six months of community service for assaulting Rihanna in February 2009.
