The saucy secretary played by Helen Flanagan, goes all out to seduce her boss - Weatherfield's ruthless businessman Tony Gordon - after he takes her for lunch at a luxury hotel.

She strips to her underwear, a sexy corset and knickers, and waits for him in the hotel room in the episode to be screened tonight.

But he rejects her and scorned Rosie decides to take revenge by revealing the truth about his fiancee Carla and her brother-in-law Liam Connor.

So she smugly shows him the footage she shot on her mobile phone of the two of them kissing.

Gordon, played by Gray O'Brien, throws the terrified teenager down on the bed and tells her that no one else must find out about Carla and Liam's affair.

And when Rosie mysteriously disappears, her family and the police soon establish that Tony was the last person to see her.

Over the coming weeks a desperate search gets under way for Rosie - with millions of the soap's fans left wondering if she has simply run away... or is there a more sinister explanation?
