Allen Leech and his girlfriend Charlie Webster split up because they "knew they weren't right for each other".
The 34-year-old 'Downton Abbey' actor and the TV presenter dated for over a year after meeting at a charity event in 2014 but quietly called time on their relationship earlier this year and Charlie insists it was a mutual decision.
She told the Daily Mirror newspaper: "We had an amazing time. There is no bad feeling at all. We are both very career minded.
"'Downton Abbey' has just finished and he is going to go on to a huge career. And my career is really exciting. It was the wrong time for either of us to be in a long-term relationship.
"I'm single at the moment so we'll see what happens in 2016."
Charlie, 33, previously admitted she had no idea who Allen was when they first met.
She said last year: "There is a running joke between us and the 'Downton' cast because I had no idea who he was when I met him.
"We were at a charity event for Centre Point in May. We were playing table football and I was thinking 'he's really lovely and very handsome and really funny, he's got a good smile'.
"We were being really competitive and I beat him. We just giggled so much and had such a good laugh.
"Then there was a quiz and we were having a lot of banter. I think that's why we clicked because we are really similar."
