Katy Perry has some thoughts about Orlando Bloom's butt

Katy Perry has accidentally declared which part of Orlando Bloom's body she loves the most.

The 33-year-old left a public message in the comments section on her boyfriend's Instagram page — beneath a post promoting his current West End play Killer Joe, reports news.com.au.

"I need a season pass for that ass," Perry wrote in the comments.

But it seems the saucy thought was meant to be private.

"Oops I meant to send that to you privately," the Teenage Dream singer added in another comment.

Last week, candid images of Bloom performing in a nude scene during the play got posted online. And yes, his bare butt featured prominently.

Of course, the actor is no stranger to being naked in public — and Perry is no stranger to witnessing it. Indeed, that's a nod to the now infamous nude paddleboarding expedition of 2016.

The West End revival of the Tracy Letts play sees Orlando play a detective and part-time hitman who becomes embroiled in a plot to murder a wealthy matriarch.
