Tamzin Outhwaite was scolded by her The Wives co-star Jo Joyner as she dropped a huge spoiler during Monday’s This Morning episode. 

The former EastEnders actress, 53, who portrays Sylvia Morgan, seemingly spoiled a huge part of the upcoming series.

The Wives sees Sylvia Morgan (Tamzin), Beth Morgan (Jo) and Natasha Morgan (Angela Griffin, 48) as three sisters-in-law who are bound together by marriage, a good glass of wine, and the tragic loss of a family member.

Channel 5’s six-part thriller, which is set to air on Sunday at 9pm, reportedly draws inspiration from Daphne du Maurier’s 1938 Gothic novel, Rebbeca.

It follows the trio of best friends trying to solve the mystery of the death – initially ruled an accident – of their fellow sister-in-law Annabelle, played by Christine Bottomley.

But during the latest This Morning’s episode, Tamzin revealed that Annabelle is not actually dead and was just missing – implying that she is found alive during the final episodes.

When show hosts Cat Deeley and Ben Shepard asked the actresses to chat about the film, EastEnders’s Jo, 47, explained: ‘There was another sister-in-law but she died.’

Cutting her off, Tamzin tried to correct her and jumped in: ‘No she hasn’t’, but Jo stares and quipped, ‘no, she has.’

Not sensing the tone, Tamzin persisted: ‘She’s gone missing’, to which Jo opened her hands and flatly proclaimed, ‘that is a spoiler’, before she pulled a face.

Realising what she just confessed, Tamzin pulled and face and corrected: ‘We think she is dead’.

Jo then clarifies that the sisters think Annabelle is dead in the beginning of the series and viewers will find out that she is in fact not dead but actually missing.

The drama unfolds during their annual family getaway to Malta.

But the trip is overshadowed by the absence of their other sister-in-law, Annabelle Morgan, who vanished a year before under mysterious circumstances.

Annabelle’s phone was found at the edge of a cliff which lead to the authorities presuming she is dead.

But the plot took a turn as the family returned to Malta –  where Annabelle disappeared.

During the holiday Annabelle’s husband Charlie introduced his new girlfriend, who has an uncanny resemblance to their former sister-in-law.

Unhappy with the conclusion of Annabelle’s case, Beth suspected there is more to the story.

The three sisters then put their heads together in an attempt to uncover the truth about what really happened.
