Sometimes people get caught doing embarrassing things, like turning up so hard to their favorite song that they forget people are watching. And, that's exactly what happened to Rihanna.
A video of the singer twerking at a party with family and friends recently went viral and it's pretty hilarious. It's not clear when the video was taken, but the "Needed Me" singer is sporting a pink wig, so this may have been back in 2014.
Anyway, as Rihanna grinds and turns up, her grandpa stands in the background chatting before noticing the singer's hot moves. Ri's reaction to being busted is priceless.
We've all been there, dancing like no one's watching before realizing that someone is actually watching. And, Rihanna's shocked expression at being spotted and the cute little dance she does as she walks away is too funny.
But, let this be a lesson to you all, make sure you're not getting too turnt in front of your grandparents.
