They’ve been happily married for seven years.
But following reports that Tom Ellis admitted to having a ‘brief fling’ with another woman, Tamzin Outhwaite has filed for divorce on the grounds of adultery.
According to The Sun, the 42-year-old actress decided to file for divorce despite trying to work through this tough time with Tom.
A source told the paper: “Tamzin desperately tried to make it work.
"Tamzin has cited adultery, so she will have a huge advantage when it comes to negotiations.
“Tom's a reasonable bloke and as it's pretty cut and dried they could be divorced within months.”
The couple are parents to Florence, four, and Marnie Mae, one, with the two reportedly planning on on remaining amicable for the sake of their children.
Just three months ago, Tamzin spoke out about her marriage to the Miranda actor, claiming that they rarely fight.
“He's [Tom] doing really well and ... it's all pretty happy days at the moment. We're not big arguers,” she said.
Over the weekend The Mirror reported that it was Tom’s decision to end the marriage with sources claiming he admitted to cheating.
The source claimed: “Tamzin is distraught. She thought Tom was the perfect husband.
“But after they agreed to separate, they had a long heart-to-heart and he admitted he had been unfaithful during their marriage.
“She’s putting on a brave face but inside she feels humiliated and is being supported by a group of girlfriends including her best friend Nicole [Appleton].”
