We’re not saying that we expected a PG-rated show from the two people who brought us “Love the Way You Lie” and “The Monster,” but they really didn’t hold back when it came to language. During the first 10 minutes of the show, we estimate that Em and Rih had already spit out the F-word about 15 times in varying form. That includes when Rih called Em an “ungrateful f–k” in the opening skit, five minutes when later she urged the crowd to “make some noise for this motherf—er,” and again when she wanted to know “how the f–k California was doing tonight.”
