Dionne, 14, said she loves nothing more than to spend the evening with the Rehab star and indulge in some pampering.
Asked how often she sees Amy, Dionne said to UK's Take 5 magazine: 'About twice a week. She's more like an auntie than a friend. My school is just around the corner from her, so I drop by for tea.
'We watch comedy movies and do girly stuff. She shows me clothes she has bought and we do each other's hair, nails and make up. But I leave the beehive to her! Amy is always cooking Caribbean food - she's really good at meatballs.'
