In the soap, Tyrone Dobbs (Halsall) is subject to physical abuse from girlfriend Kirsty, played by Natalie Gumede.
"People say, 'How do you feel when he's getting beaten?'," Hudson told What's on TV.
"But I don't see Tyrone as my husband, he's much quieter than Al, who's really in your face and very funny.
"I think the storyline is really good, they're doing a brilliant job. Natalie is amazing at playing a psycho."
The soap actress played Katy Harris in Coronation Street from 2002 to 2005, and more recently starred in Wild at Heart, which finished in an emotional final episode on December 30.
