Katy Perry on Mysterious Spiritual Journey

ABC News' Cecilia Vega and Kim Berryman report:

She's known for kissing other girls, and hanging with California girls.

And just when it seemed like this superstar's career couldn't climb any higher, Katy Perry tweeted a picture of herself, quite literally, on top of the world.

"I ate, I prayed, I climbed a volcano," Perry tweeted along with the photo Wednesday to her more than 26 million followers.

Sound vaguely familiar? Julia Roberts starred in the 2010 film based off the best-selling book about a woman on a spiritual journey mission to take "two weeks off to, you know, deal with everything" and go some place where she can "marvel at something."

Perry is on an "Eat Pray Love" journey of her own, from mysterious mountains to meditations, tweeting all along the way.

On Monday she wrote, "Getting some (expletive) out my chakra's!"

Over the weekend, "Starting the day with a group meditate #breakfastofchampions"

And another, "I can feel the phoenix rising."

Why a 27-year-old would need to do all this soul searching is unclear. However, it may have something to do with the high-profile divorce from Russell Brand.

Or perhaps she's attempting to get her mind off the recently rumored relationship with John Mayer.

But no matter what, this daughter of evangelical parents is on a spiritual quest.

Perry told Elle magazine she has crystals and a mantra. She's just not saying what it is.

"I can't tell you that. I wish I could. It's really good. It might be my last words. It might be part of my last dying breath," Perry said.
