Pop star Katy Perry relies on her husband Russell Brand to keep her grounded because she can easily get swept up in the "fabulousness" of showbusiness.
The singer has become a staple at the top of pop charts across the world since shooting to fame in 2008 and she admits the success has occasionally gotten to her ego.
But Perry has British comedian Brand to thank for bringing her back to reality, as he's taught her not to take anything for granted.
She tells Vanity Fair magazine, "Sometimes I can be distracted by the glamour and the fabulousness. But my husband always reminds me to keep the core intact, because that's what matters.
"I just think I have to appreciate every day, every opportunity, work hard, and continue to evolve as an artist. I already know my future evolution, where I'm going to go."
