Catherine Tyldesley didn't need to do much research for her Corrie role as a scorned woman - because she's suffered the same fate herself.
The actress, 32, plays Eva Price, whose boyfriend Aidan Connor is unfaithful to her in the ITV soap.
She told Woman's Own magazine: "I have been cheated on. I've poured nail varnish into game consoles and thrown phones in canals.
"I'm perfectly qualified to play a woman scorned!"
On Friday, Corrie fans will see Shayne Ward's character Aidan cheat on Eva with Maria (Samia Ghadie).
Catherine, who has settled down with husband Tom Pitfield and their one-year-old son Alfie, told the mag: "Every single boyfriend has cheated on Eva, so she sticks firmly to that girl rule where you don't go with another girl's guy.
"So it can't be long before the truth will out and it hits the fan."
