Madeline "Madi" Diamond is a classic Princess: needy, vain, gorgeous and high maintenance. Madi was the apple of her father's eye when her parents were together and took the break-up of their marriage personally – why would her dad leave her? As a result, Madi's self-confidence is on the floor. She desperately seeks affirmation and wants to be adored.
Following in her father's footsteps, Madi has grown into quite a vain creature – spending hours applying make-up, fake tan and false eyelashes. Given free reign of her dad's credit card, Madi will think nothing of spending big wads of his cash on getting her eyelashes permed, if it makes her more eligible. We first see Madi when their mother publicly dumps her with her younger brother Zack at Waterloo Road and she comes face to face with her biggest competitor for her dad's affections – Sian.
Used to getting her own way, Madi will get into a sulk if she doesn't, which Lauren, Trudi or Vicki would have no patience for. She soon finds Ronan's easy-going, cocky sense of humour reassuring, and his confident attitude builds her own confidence. Madi becomes a devoted friend to him, but their friendship grates on Vicki.

- "I never wanted to come to Waterloo Road. My parents split up, I had no-one to talk to. I had a wicked stepmother, and life was generally awful. But I'm getting to know her, and I think I really like her. Changing lanes, coming here, has brought us all closer together. My dad's a PE teacher, and my wicked stepmother turns out to be not so wicked, most of the time. You know, it's taught me that changes, even if they are scary, can be good. And Waterloo Road has supported me through it. Sian's a science teacher, and she is really great. It's a great school, and coming here has made me a happier person."
