Britney Spears says she had a transformative experience -- quite literally -- after watching the movie Big Eyes.

The 38-year-old pop star took to Instagram on Saturday (Aug. 8) to gush over her Tim Burton (her "favorite director in the whole world") and his 2014 drama about American painter Margaret Keane, whose husband took credit for her popular big-eyed portraits of children in the 1950s and '60s.

In her post, Spears first gives a short synopsis of the empowering film, which stars Amy Adams and Christoph Waltz, before segueing into a story about an eye-opening photoshoot she had after the screening.

 

"It was very weird the same day I watched this movie I did a mini photoshoot and look how freaking big my eyes were !!!" the singer wrote alongside the photoshoot pics. "I mean … my eyes have never been that big !!! It’s actually kinda crazy and they aren’t retouched at all … coincidence maybe ???"

Spears added that she learned an important lesson from the whole experience.

"If the power of what you see and hear can influence your life THAT much … I mean literally stay away from bad people and raise your awareness with high energy people !!!" she continued. "That’s what I learned from this … and watch Big Eyes while you’re at it !!!"
