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
Well this is an inneresting development!
Hmm.. guess KStew isn't too afraid to show her face if there are party favors involved!!
While it's unsure who was hosting the party, we've heard it was somewhere in Orange County… which makes sense since Lindsay's brother came to town for some pro-surfing!!
Wow… maybe a budding friendship could prove mutually beneficial for the two. Kristen needs a shoulder to cry on and LiLo needs a good Hollywood friend!
