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!

We take it Zach Braff isn't a Belieber??
We're not sure why he'd want to tease the teenager Canadian pop star, but Justin Bieber was served up some serious shade on Zach's latest Vine video!
Maybe he's not a fan of the Biebs' musical skillz or maybe he has a problem with his pet treatment, but whatever the reason, Zach is putting the Biebs on blast…
…well, in a kind of "interpret it how you want" way.
You've gotta see the inneresting video that speaks volumes!
