Lana Del Rey says she feels her most confident when she is happy.

The singer told BBC Radio 1's Zane Lowe that a number factors can affect her happiness, such as her "environment" or hearing the perfect song.

She said: "I think for me, what makes me confident changes every day...but generally I would say confidence for me just comes from being really happy.

"And that could be anything down to my environment or being lucky enough to have my muse with me or [hearing] an amazing melody for the first time."

Del Rey meanwhile also touched on diversifying into different fields, saying:

"I would feel at any point in my life that it was never too late to just sort of switch into any different lane or any different vein, you know, just to kind of be free enough to sort of explore things. I think that being worried about whether or not you're ever going to make money, I think that trips people up a lot."
