Katy Perry is going to let it all hang out — or at least almost all — to promote her upcoming album, judging by a new photo tease from Esquire magazine.

Perry is just beginning to ramp up promotion for her new album. The “California Gurls” was released June 20, she has a video out and the album following on August 30.

That means Katy will be making the rounds of magazine interviews and talk show appearances.

She debuted her new single live at the MTV Movie Awards Sunday (June 5). It’s her sexiest single yet and featured bikini-topped dancers.

Katy wore a weird Wonder Woman outfit and rapper Snoop Dog makes an appearance toward the end of the song.

Snoop introduces the song in her new video, a sugary confection with Katy wearing delectable deserts on breasts. (see it below)

Katy has one of the hottest bods in music and it looks like she intends to deploy all of her assets to move the record.

In the Esquire photo on a well placed arm and hand conceal he bare breasts. Despite her ample proportions Katy has never appeared fully topless.

Katy said she was inspired to write a song about California after hearing Alicia Keys and Jay-Z’s tribute to New York in “Empire State of Mind.”
