According to one critic of her performance, RiRi showed up 40 minutes late to her own concert, and instantly started grabbing her crotch when she came on stage (not the way you're thinking, but ew).
"More than 40 minutes late, she appeared on-stage sporting a mullet and within the first minute had begun grabbing and rubbing her crotch - something that continued unabated for most of the show…While slurring marked the first half of the show, it was her disinterest in singing along to more than half the words of each song that marked the second half."
Oh na na come on, Rihanna! We know crotch grabbing isn't exactly a new habit for you, but that doesn't make it cool/sanitary.
And sure, we're aware that you've over-indulged in the past at the concerts of others, but at your own? This news is pretty disturbia!
If all this is true, we hope her Aussie fans got a RiRiRefund!
