The actress - who played Rosie Webster on the hit soap - claimed that she was once convinced that a man had sneaked under her bed during a stay at a hotel, only to discover she'd seen her reflection in a mirror!
She also told of another hotel where she refused to wear a robe, thinking it cost £100 - unaware that she would only have been charged if she'd bought i!
And 22-year-old Helen later revealed that she spends £400 a month on her hair.
Vowing to "make up for my patheticness with my boobs", she put on a bikini as she prepared for her first Bushtucker Trial.
"Do you think it looks stupid?" she asked Linda Robson and Charlie Brooks. "Yes, it probably does a bit. I’ll put some more clothes on."
"My advice would be to put something on. It might look like you’re trying a bit hard," Linda suggested.
It was wise advice, as Helen's challenge involved her being locked in a coffin with hundreds of critters crawling all over her.
