Mabel has "learned a lot" from Harry Styles.
Mabel
The 23-year-old singer previously supported the One Direction star on tour and thinks his positive outlook is something to emulate.
She said: "He brought the same kind, beautiful energy to every person I saw him meet. I didn't see him have an off day.
"Sometimes, when I'm feeling anxious or low, I have a tendency to be like, 'Not today'. But I learned a lot on that tour, that we're so lucky.
"He just has that positivity - it oozes out of him. He's a rock star, he's Mick Jagger."
And Stormzy has been another mentor for the 'Don't Call Me Up' hitmaker.
She told Grazia magazine: "He knew who I was before 'Finders Keepers'. He's always been so kind and supportive, he'd be like, 'You're doing your thing'. "
The 'Fine Line' singer thinks it is "vital" to have female collaborators and finds it frustrating when women are pitted against one another.
She said: "It's all about supporting each other and encouraging other women to be producers and engineers.
"It's a crazy concept that, as females, we're pitted against each other, like Rihanna or Beyonce, Cardi B or Nicki Minaj. But why would we compete? We're all different. We're all in different lanes. We need to stand together."
Mabel - who is the daughter of singer Neneh Cherry and producer Cameron McVey - was just five years old when she wrote her first song.
She said: "I wrote this love song to a boy in my class. I hadn't figured out how to play chords yet."
