Keegan opened up for the first time about her break-up with the Wanted member, to whom she was also engaged for some time, in an interview with Hello magazine.
"Obviously it was a very sad time for us, as we were together for 19 months. But I got to think of it as, 'I'm not the only girl who has ever had a break-up'," the star said.
"The worst part for me was having the whole thing played out so publicly. In the end, I had to simply ignore the gossip and throw myself in my work.
"I was really busy with some great storylines and my friends were amazing. But eventually you just have to let things go and get on with life. I'm in a much better place now."
Her character Tina McIntyre has been in the forefront of Corrie this autumn with a surrogacy story that impacts upon her relationship with Tommy Duckworth (Chris Fountain).
Keegan, who was recently linked to rugby player Mark Flanagan, has set out her desire to meet the "right guy" in the near future.
