This might be Rihanna's most NSFW video to date.
This video is certainly not for the faint of heart. HA!
Coldplay frontman Chris Martin made a minor musical booboo at his concert in Washington DC this past weekend, when he began playing classic tune Warning Sign…
But he's SO charming about the minor mishap, that we are instantly forgiving and love him even more for his humble demeanor.
In fact, everybody LOVES it when celebs make mistakes, especially when they so cutely address the issue.
Makes them a little more human, right?
Ch-ch-check out Chris' adorable oopsie (above)!
