Sanderson, 32, said she has signed a new contract to stay in the show for at least another year, Digital Spy.
"I'm really happy here. I've recently signed a new contract and I'm going to be here for quite a while yet - it's another year with an option for another year," she said.
Sanderson revealed that she has no idea what her character is going to be look.
"But I don't have a clue what I've actually signed up for. They haven't told me anything about what they've got planned for my character. I need to have a proper meeting to find out what's happening next. It was a very easy decision for me - but it's never a formality in this job because it's not up to me.
