Celebrate high times - come on!
We're guessing Rihanna is enjoying her Labor Day weekend if these videos are any indication!
In fact - she's having a ganja old time, ha!
Watch Rihanna getting her party on down
We only wish this High School musical included Zac Efron, LOLz!
Otherwise, this performance was pitch perfect!!
High School was not the best time in many people's lives, but it may have been the best performance of the night at the Billboard Music Awards!
Ooh, will there be a kiss? Find out!
