Noted heterosexuals The Wanted have claimed bouncers told them to "face the wall" when Britney Spears walked down the corridor when they supported her in Manchester last year. But not because of their erections!!!!
Siva recounted the incident to Fresh 102.7 (as quoted here) using these words: "I was in the hallway with my tour manager. Basically we were looking with a laptop, trying to get WiFi, facing the middle of the hallway… (Britney's) bouncers came down with her and told us to face the wall… We turned around and I faced a wall for about 10 seconds until she got really far away."
They apparently did get to have some photos with her in the end, so that's okay.
