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
This has already been quite an eventful birthday for Miley Cyrus!
The singer’s home was broken into on Friday night, but she wasn’t planning on partying it up for her big 21st bday moment anyway — Because she’s focusing on work!
Mileybird is going to sing her heart out at the AMAs on Sunday, but after that… Let the games begin!
And since all of the other celebs will be in town we can only imagine how star-studded this will be!
We can’t wait to see pics!
