ANDREA Tate will be left horrified in Emmerdale next week when Graham Foster threatens her over their secret affair.
The unlikely couple had a one-off one-night stand years ago and Graham will soon become convinced that little Millie is really his daughter.
When the tot is rushed to hospital after an accident with one of the Home Farm horses, Graham is staggered when he hears Andrea – who’s played by Anna Nightingale in the ITV soap - tell the medics Millie’s date of birth.
Later he confronts her and asks her if Millie is his daughter. While Andrea denies the possibility, saying she’s 100% Jamie’s, Graham reads her panic as guilt and decides he must be Millie’s biological father.
When he doesn’t get any answers from Andrea, a furious Graham – Andrew Scarborough - leaves an angry voicemail on her phone, threatening to reveal everything if she doesn’t tell him the truth.
But what will Andrea do?
Andrea and Millie arrived in Emmerdale earlier this year, shortly after Jamie. Jamie’s mum, Kim Tate, was stunned to discover her long-lost son had a wife and daughter he’d failed to mention.
Fans were also shocked after predicting romance for Jamie and his vet co-worker, Belle Dingle.
It soon became clear that Andrea and Graham had their own secret history however.
It was revealed that Graham – on Kim’s instructions – had hired barmaid Andrea to keep an eye on Jamie.
Graham was in the throes of alcohol addiction at the time and was unable to do the job himself.
But he didn’t bank on Andrea actually falling in love with Jamie. Andrea has been keen to keep the truth hidden from Jamie, promising she genuinely loves him.
