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
Mmmm. We could TOTALLY listen to Colbie Caillat's beautiful voice all day.
Or you COULD mosey on over to iTunes by clicking HERE and purchase her brand new EP Gypsy Heart for even more Colbie tunes!
