R&B star Rihanna has postponed the start of her North American tour due to "production delays".
The "Diamonds" hitmaker was slated to kick off her Anti trek in San Diego, California on 26 February (16), but now that date, as well as her first eight stops throughout the US, have been shifted from February and March to May (16), reported E!Online.
A representative of the 27-year-old singer cited "production delays" were the cause for the postponement.
The news comes days after she pulled out of a planned performance at Grammy Awards at the last minute, citing vocal issues.
