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
They’re keeping a loving eye on her!
The actress was seen helping out with the shopping on Saturday at Costco in Thousand Oaks with her mom and dad by her side.
She also showed some super strong willpower because we didn't see the actress pick up even one delicious sample!
And can we just say how cute Miz Bynes was in her monochrome ensem?!
Looking good, Amanda!
