Russell Brand slams ex-wife Katy Perry's 'vapid' lifestyle

Russell Brand does not hold back talking about what led to his divorce from Katy Perry in 2012.

In the 40-year-old comedian's new documentary, BRAND: A Second Coming, he says he couldn't handle the celebrity lifestyle that went along with being Perry's husband.

"Oh my f**king god. I'm living this life of the very thing I detest," Brand says in the trailer for the film. The Get Him to the Greek star is heard calling fame and power "bullsh*t" as footage of him and Perry walking through a crowd of paparazzi is shown. He says that he didn't want the life of a "vapid, vacuous celebrity."

According to the Daily Mail, another scene in the documentary has Brand admitting to his friend, Stephen Merchant, that after a trip to Africa with Perry in 2010, he realized there was "not a resolution to anything spiritual." He adds that "at some point, to be happy, I'm going to have to walk away."

Brand married Perry in 2010 and and filed for divorce 14 months later. The 31-year-old pop star told Vogue in 2013 that Brand told her he wanted a divorce over text message.

She also blamed the demise of their marriage on him not being able to handle her being "the boss" on tour.

"At first when I met him he wanted an equal, and I think a lot of times strong men do want an equal, but then they get that equal and they're like, I can't handle the equalness. He didn't like the atmosphere of me being the boss on tour," Perry said. "So that was really hurtful, and it was very controlling, which was upsetting. I felt a lot of responsibility for it ending, but then I found out the real truth, which I can't necessarily disclose because I keep it locked in my safe for a rainy day. I let go and I was like: 'This isn't because of me; this is beyond me.' So I have moved on from that."

One person that's a fan of Perry's celebrity status is presidential candidate Hillary Clinton. The "Roar" singer took over the former Secretary of State's Instagram this past weekend and snap some fun photos. Check them out:
