The Hollyoaks actress, 36, attended the British Soap Awards last night dismissed the rumours.
She told The Sun: "I just speak to Dan about Lexi [their four-year-old daughter] and that's it. I've no idea how I've got involved in this."
It was claimed last week that Stephanie and Corrie star Kym, 38, were having to be kept apart at the awards bash because of their feuding over personal trainer Dan.
A source told the Mirror: "This should be all about the drama on-screen rather than between the stars. So Organisers will be on high alert."
But Stephanie insisted that she was focusing on Hollyoaks and not the alleged drama in her personal life.
She added: "I'm really looking forward to tonight and I'll be at the after party. This is about Hollyoaks and celebrating our hard work."
Dan and Kym are rumoured to have called their engagement off last week, following blazing rows about Stephanie.
However Dan took to Twitter to insist they had not split up and were simply taking a break.
