"Rihanna has posed for a raunchy backstage photo ahead of the latest date on her &amp;#039;Diamonds World Tour&amp;#039;. The singer was wearing just a pair of yellow knickers as she got her hair styled before the Atlanta concert, using a towel to cover her boobs.  The &amp;#039;Stay&amp;#039; star uploaded the image to Instagram along with the caption: &amp;quot;Show time!&amp;quot; The latest topless picture comes just days after Rihanna shared a series of bikini shots with fans, as she celebrated Weed Day. The 25-year-old was recently forced to deny reports that she is pregnant with Chris Brown&amp;#039;s baby after cancelling four concerts due to illness. &amp;quot;[She] is just sick, and that&amp;#039;s really it,&amp;quot; a source said. &amp;quot;I know, that&amp;#039;s not a good enough reason because everybody wants some drama and the rumours that she&amp;#039;s pregnant to make the rounds, but sorry, not this time. She&amp;#039;s not pregnant.&amp;quot; View all of today&amp;#039;s best celebrity pictures - Photo gallery:  "^^<http://www.w3.org/2001/XMLSchema#string>
