As you can see in this video, ex-Pussycat Doll Ashley Roberts is going off the rails tonight in I'm a Celebrity's Terror Train.

Rusty and choc-full of rotting meat, you might be forgiven for thinking the singer has boarded a 1980s InterCity train and headed for the buffet car.  As it happens, she's not, but her experience still manages to scare the life out of poor Ashley.

That isn't the train's whistle you can hear in the clip - it's Ashley's shrieks...

Maybe she could use it as a sample in her next song?
