Hollyoaks star Anna Passey doesn’t think her character Sienna Blake could become a killer.

The barmaid has become quite a psychopath in her bid to steal Nancy Osborne’s husband Darren and has a dangerous obsession with their baby son Oscar.

But Anna told Inside Soap magazine: “You can’t move five steps in Hollyoaks village without running into a murderer, can you? I honestly couldn’t tell you if Sienna will become a killer.

“My instinct is that she isn’t, because she always believes what she’s doing is the right thing.

“With her upbringing, she isn’t an out-and-out evil person. She really believes she’s got her reasons to do what she does.

“But you never know – this is Hollyoaks!”

While Sienna may be confident enough to try and act as a real mother to Oscar, Anna admits she was nervous acting with the babies who play him at first.

She said: “We don’t really have babies in my family and so I was a bit nervous the first time, but they’re adorable.

“It’s a highlight to work with them, definitely.”
