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
SPOILER ALERT: DO NOT WATCH THE FOLLOWING CLIP IF YOU DO NOT WANT A PLOT POINT IN THE MOVIE RUINED FOR YOU!
What a nice way to tie this film the previous ones!
Check out the aforementioned clip, which features Jennifer Lawrence as Mystique morphing into the adult version of herself, played by Rebecca Romijn in the original X-Men trilogy (above)!
Nice! And SEKSI!
And apparently, this isn't the only surprise cameo either!
But we'll let you see that one for yourselves!
What do U think?? Will U be checking out X-Men: First Class??
