The Girls Aloud star said she hasn't ruled out becoming an actress and joked that she could join Albert Square as Bianca Jackson's little sister.
"As soon as I get home I get into my neon tracksuit, get into bed, I've got my little dogs, and put on EastEnders," she told PA. "I find it really helps me forget about the rest of the world for half an hour. And if I've not been able to watch it for ages I'll have like seven or eight episodes in a row.
"I did a little bit of acting on the video for 'Yo-Yo', because I wrote the song. I wrote the story to the video and I had to kind of act the video a little bit. I didn't know if I was going to be able to do it, but actually I really enjoyed it.
"If I was to have lessons and get better - I was surprised that I enjoyed doing it on the day. I could be like Patsy Palmer's younger sister or something!"
Roberts recently started work on her second studio album following the release of her debut solo effort Cinderella's Eyes earlier this year.
