Katy Perry climbs volcano

Katy Perry climbed a volcano and had this photo taken.

The 'Part of Me' hitmaker has apparently been taking inspiration from Elizabeth Gilbert's post-divorce memoir 'Eat, Pray, Love' in making a trip to see some spectacular sights.

Referring to the title of the book, Katy - whose divorce from Russell Brand was finalized in July - tweeted alongside a picture: ''I ate, I prayed, I climbed a volcano.''

It seems the brunette pop star has been getting in touch with her spiritual side recently, meditating and cleansing her ''chakras''.

She tweeted on Monday: ''Getting some s**t out my chakra's! #eloquent (sic)''

And two days earlier she wrote: ''Starting the day with a group meditate #breakfastofchampions (sic)''

Meanwhile, Katy has signed up to perform at a fundraising concert for US President Barack Obama.

According to the Hollywood Reporter, the 'Wide Awake' hitmaker will be one of several artists who will perform at the 30 Days to Victory concert at Los Angeles' Nokia Theater on October 7.

Tickets start at $44 for supporters under 40, while general admission seats will be $250.

A dinner with the president at a nearby restaurant will follow the concert, with tickets costing $25,000.
