Marie Louise Agate (born May 16, 1995) is one of Wendy's daughters. She is the older sister of Amie and Mary-Anne.

She came across as being very mature for her age and admitted since Supernanny came that Mary-Anne's behaviour was more under control.

She was 10 at the beginning of the show and now is 23 years old in 2018.


  • "Since Supernanny's been here, mum hasn't let Mary-Anne walk all over her, and we've actually got some time with her."
  • "Mary-Anne, with you, life is miserable."
