Shona also revealed how despite splitting last year she is not ready to move on just yet.
"I'm not ready to date anyone else at the moment and I think it's really important to have some time by yourself," she added.

"And EastEnders has been a great place to grow up. I've been so lucky to have so many wonderful people around me."
The actress has played Whitney in the soap since 2008.
Shona, who also dated her co-star Matt Lapinskas in 2012, said she was in a "good place" now she's single.

She said: "I feel great. I'm 28 and I'm in a good place. I'm enjoying spending time with my family, especially my sister.
