The former 'EastEnders' actress has cited adultery as the reason for her split from the 'Miranda' star, The Sun claims.
Tamzin and Tom in happier times
It is thought Ellis had a brief fling with another actress while filming 'Gothica' in the States earlier this year. He has now moved out of the family home.
A source told The Sun: “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 have two children together, four-year-old Florence Elsie Ellis and one-year-old Marnie Mae Ellis.
Last month, when it was first announced that they were separating, a spokesperson said: "Tamzin Outhwaite and Tom Ellis are sad to confirm they have separated. They continue to support each other as parents and will remain friends. They ask for sensitivity at this difficult time."
