We aren't sure what's happening deep in the heart of Texas, but it ain't good!
Rihanna was supposed to put on an epic concert tonight in Houston as part of her Diamonds World Tour, but now it's not happening!
Due to an undisclosed illness, the Where Have You Been singer won't be taking the stage at night at all!!
Uh oh!! We hope it's nothing too serious!
This isn't the first time RiRi has disappointed fans, of course — she canceled concerts in Boston and Baltimore last month because of laryngitis!
We feel soooo terrible for those excited members of RiRi's Navy who thought they would see their Only Girl in the World sing to them tonight!!
Live Nation is cautioning ticket holders not to throw out their stubs because the event will be rescheduled.
Luckily for fans a few miles down the road, Ri is still expected to perform as promised tomorrow in Dallas.
