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
Katy Perry and John Mayer have been spotted hanging out - and swapping saliva - ALL over El Lay the past few weeks, and last night was no exception, as the pair were hounded by paparazzi as they left a house party in Los Feliz!
Just look at them (above)!
They may not have been holding hands, but we're sure they were saving THAT for the car ride!
Perhaps they were on their way to another Four Seasons sleep-over!
Oo la la!
C'mon, guys! Spill the deets!
