The actress, who played Katy Harris from 2002 to 2005, revealed that her high-profile 'Killer Katy' plot - which saw her alter-ego killing dad Tommy (Thomas Craig) in a rage - leaves her particularly red-faced.
Speaking to the Sunday Mirror, she explained: "I die, I absolutely cringe. I was quite poorly when I was doing that storyline, because it was quite heavy and I was living every moment of it, so I looked a state."
She added: "I struggled in Corrie. I loved it, but not the attention. I couldn't leave the house without a cap and shades on. I don't know how to deal with the attention, I get embarrassed. I feel like I've got a bit of my life back now."
Hudson recently tied the knot with her former co-star Alan Halsall (Tyrone Dobbs) in a Cheshire ceremony.
