Speaking to Digital Spy, Foote teased: "Now that Katy is 18, I've actually started having quite a few Rovers scenes which is really exciting - especially working with Sue Johnston now that she's joined the show.
"I recently had a scene with Sue where I was quite snappy towards her character Gloria, so afterwards I apologised to her! It was my first scene with her so I didn't want to offend her!"
The young star also spoke about her upcoming surrogacy plot in the wide-ranging interview.
Watch Katy introduce the surrogacy idea to Gary in a preview clip of this Thursday's episode:
