Katy Perry Spent 'So Much Extra Money' making THIS ‘right’

Katy Perry recalls the ‘bad’ tan.

When Katy Perry created one of her most recognisable music videos, she was in a foul mood.

In a video released by Vogue on Friday, the Grammy Award nominee, 38, discussed her "Life in Looks" and revealed why she had to "spend so much extra money on colour-grading" her 2010 music video for "California Gurls."

"Funny story behind this is that I look super tan here, right?" she recalled.

"Rarely do I get spray tans, and typically you're supposed to get them the night before. Well, I just didn't have time. So, I got them the day of my music video."

Katy Perry  keeps 'getting oranger and oranger and oranger'

"When you get a tan the morning of your music video, your colour changes gradually throughout the day. So, I just kept on getting oranger and oranger and oranger. We had to spend so much extra money on colour-grading this music video because in one part of the video, I'm this colour orange, and then I'm this colour orange in the next part of the music video," added Perry.

Then she gave some wise advice to her fans: "Kids, just a little tip: fake tan, night before."

California Gurls, the lead song from Perry's third studio album Teenage Dream, was released in 2010 by Perry.

She appears in the video sporting a variety of sweets as she explores a setting reminiscent of Candyland with Snoop Dogg, some unpleasant Gummy Bears, and other friends.
