The presenter said that she thinks the 19-year-old, who was 'made under' on Frost's show Snog Marry Avoid?, is a "lost young girl".
The 32-year-old told Now: "When we made her under she looked amazing. But unfortunately she didn't keep it up."
The former Atomic Kitten singer added that the hopefuls in the new series of the show are not improving.
She admitted: "The candidates are worse than ever. They've really outdone themselves this time."
The fourth series of Snog Marry Avoid? airs on BBC Three.
