Rihanna postpones Houston concert due to illness

After cancelling shows in Boston and Baltimore last month, R&B star Rihanna rescheduled her Diamonds World Tour show in Houston.
The 25-year-old singer had to cancel her show due to a recurring illness, reported Us magazine.
She was set to perform on Tuesday at the American Airlines Center in Dallas but a recurring illness forced her to postpone another stopover in her tour, meant to support her seventh album "Unapologetic".
The 'Umbrella' hitmakers concert in Texas is the latest in a series of cancelled tour stops, following the deferent of her Boston and Baltimore shows in March.
Although it was not specified as to what illness she has been stricken with, a source revealed it is a returning case of colds and laryngitis.

"It sucks. She hates letting her fans down and it drives her crazy when she's not on stage. She feels bad, but what can she do? She just laying it down, trying to get better," a source said.
The concert's promoter have advised ticket holders to keep their stubs as the show will be rescheduled.
