Their relationship ended soon after and Rebecca went into therapy to help her with trust issues. Writing about her former relationship with Seann, whose cheating scandal came to light on Rebecca’s birthday, she framed him as “toxic”. Rebecca said: “For a short time I was one half of the poster couple for toxic love. I didn’t even know that love wasn’t supposed to be like us, that an insidious loss of joy, opinion, and self-confidence wasn’t what was required of me. “I just thought that relationships took work and compromises, and that they weren’t always easy, and a whole host of other useless soundbites that I had removed over the years to justify the daily pain. “Here’s another thing about toxicity – once you know it, you see it everywhere. After I left him, my eyes were opened to the toxic messages that were poured into pop culture.” Rebecca went on to write in The Guardian that Seann was a ‘gas lamp’, adding: ‘In the two years since the Strictly incident, I’ve worked really hard to get the sticky, tar-like residue that gas lighting leaves on from my body. I met someone new.” Rebecca, who works as an actress and writer, said she was left “devastated”. She added: “I would never get rid of toxic love – ever – if I didn’t recognize that the only thing all the toxic situations in my life had in common was me.” ITV bosses hope comic Seann will finally come clean about his snog with professional partner Katya, 33. Their shocking romance ended the dancer’s marriage and his own five-year relationship. The comic has never gone into detail about his romance with Katya and ITV bosses hope life in the jungle will give him the perfect opportunity to finally tell all. A source said: “Seann is an incredible signing for I’m A Celebrity and is a real coup for ITV. “His snog with Katya is the biggest scandal to ever hit Strictly. People are still talking about it. “Seann has joked about his snog with Katya in his comedy skits, but has never gone into detail about their relationship. “Life in the jungle is boring and those long hours around the campfire would be the perfect time for Seann to talk. “He can’t avoid it, as he is best known for that snog. “It’s unlikely that his teammates won’t mention it. It’s not going to be an easy watch for Katia or the people who are burned by their romance.” 3 Rebecca, who works as an actress and writer, said she was left “heartbroken” Credit: Getty – Contributor
