Listen to Red Hot Chili Peppers on iHeartRadio

The Red Hot Chili Peppers are at the center of another, much smaller Super Bowl controversy about nipples. 

According to "Deadspin," the FCC received a total of 53 complaints about the big game last month, and a number of them had to do with the fact that Anthony Kiedis and Flea took the stage topless. 

One angry viewer called it a "gratuitous display of nudity" and argued that if Janet Jackson can't "show a nipple," these guys shouldn't either. Others brought up Jackson's 2004 wardrobe malfunction, and said that allowing the Chili Peppers to go shirtless was sexist. 

But it wasn't just the amount of skin that made them upset.  Some of the complaints also targeted Kiedis' pelvic thrusts, Halftime headliner Bruno Mars' sexually suggestive lyrics, and the amount of inappropriate Super Bowl ads this year.
