The 411 tell Radio 1 their debut video for ‘On My Knees’ got the girls all gasping for breath in tight corsets – and as they explained it wasn’t very pleasant. “I was corseted in good and proper,” one said. “The worst thing is as well not only are you in the corset which is tied up really tight, they sew it to what whatever you’re wearing below. So if you want the toilet, bad luck!” Another added, “Mine was an all-in-one. Make sure you go to the loo before you put that on! The weirdest thing was when you took them off I felt so funny because you’ve been held in all day and then all of a sudden your stomach would just release!” The tune includes Ghostface Killah.
