Cover girls aren't the only folks concerned about, um, well, internal housekeeping if you will. Pearl Jam frontman Eddie Vedder is trying one detoxification diet on for size: the Master Cleanse.

"I just finished touring, and I'm on a detox thing," Vedder discusses with 'W' star Josh Brolin in November's Interview magazine. "It's a heavy detox, so nothing in my belly except water, salt and cayenne pepper. I'm doing the Master Cleanse, which also means I'm not smoking. I haven't smoked for four days. This is probably the first phone conversation I've had in 10 years where I haven't had a smoke. It's like trying to talk without using adverbs."

Vedder says the upcoming presidential election prompted him in part to attempt the body flush. "Yeah, that's why I'm detoxing this week," he tells Brolin. "It's just to set myself up for next month."

"Being on the road a lot... I'm ready to just clean up my act," Vedder continues. "I don't know how it's all going to come out -- this is, like, four days in. In fact, I don't want to talk about it. But it does feel weird. I'm feeling different ... I'm kind of walking around in a daze, wondering if this is all really happening."

Now Vedder knows what it's like to walk in Beyonce's shoes.
