Tori Kelly "picked up" tips from Professor Green on how she should deal with fame.
The 'Should've Been Us' singer collaborated with the British rapper on his 2014 hit 'Lullaby' before she became a chart success herself, and confessed she would "follow" her new pal and copy his techniques on handling the music business.
Speaking exclusively to BANG Showbiz, she shared: "With Professor Green, he has been doing it (music) for so long, so even just being around him I naturally picked up things like how he did his interviews, how he deals with his fans, and all the publicity and stuff and getting to kind of follow him and shadow him in a way.
"I felt like he taught me a lot without really saying it, just being able to watch him and watch how he flows."
And the blonde beauty says she is glad her famous pals are in the music business "for the right reasons".
Speaking about 'Thinking Out Loud' hitmaker Ed Sheeran - who she met when they were both struggling to get noticed through their YouTube videos - she added: "I try to keep in touch with them.
"I saw Ed at the Global Citizens festival and it was literally seconds before he went on stage and he stopped to say hello.
"It's cool to keep running into people like that, that I know and have a lot of respect for ... It's cool that I've got to know and work with really solid people that are in it for the right reasons."
