Tyldesley's alter ego Eva has an upcoming romantic moment with Nick Tilsley (Price) interrupted by Gail Platt (Helen Worth).
She told ITV.com: "Ben is an absolute joy to work with. I am very comfortable around him and he never fails to make me smile. So kissing scenes don't feel awkward - which makes the job so much easier."
Of her character's clash with Gail, the star added: "What interests me is that this time, Gail has met her match. Eva is determined to stick this one out and has genuinely fallen for the Street's best catch."
Meanwhile, the 29-year-old actress admitted that she found it difficult to say goodbye to close friend and former co-star Katherine Kelly, who quit after six years playing Becky McDonald.
Tyldesley added: "We were all very sad to say goodbye to Katherine Kelly last month. Kate has been like a sister to me for many years.
"I'll miss her and I'll miss Becky. I'm so proud of what Kate has achieved with Becky, she has certainly made her mark. Becky has to be one of my all time favourite Corrie characters."
