Sienna Miller has had the word ‘slut’ spray painted on her house.

The British actress’ public image took another body blow following her much-criticised affair with married boyfriend Balthazar Getty after vandals wrote the insult on the outer wall of her North London home.

So who would do such a terrible thing? Well, of course, there is the legal wife or several children of the guy she is currently bonking senseless.

Then there is her jilted ex-lover Rhys Ifans. But Hecklerspray would like to make it very clear that we don’t think it is any of these people. Pointing the finger would be just wrong.

Plus the fact that Sienna Miller is so unpopular at the moment the list of possible culprits is too long to narrow down.

Sienna Miller should have just stuck with P Diddy. They were so happy together. He’d treat her like a lady, and she’d giggle at all his fall-flat jokes. Also, he’d send his stooges to bang on the car doors of anyone taking pictures of their secret meetings.

Then again, perhaps Miller should have stuck to Sean Penn. They’d be oh-so happy too – and his wife maybe didn’t care quite as much.

‘As much as who,’ you may be wondering. As much as the wife of Balthazar Getty – the guy she got photographed canoodling with while her nipples and breasts apparently substituted as stress-balls for Getty’s super-tense fingers and palms.

You remember that, right? Of course you do. Everyone else seems to as well. That’s why the Sun says:

“An exterior wall of Sienna’s home in North London was daubed, in capitals, with the word ‘SLUT’. The black, spray-painted graffiti also included an unsettling circular symbol – which looks like an attempt to recreate the sign for Satan. The actress has attracted controversy for her relationship with married man Balthazar Getty.”

A satanic symbol written in black? Then it wasn’t Mrs. Getty – she hates devil stuff. It was Britney Spears – that’s her bag, right?

Not anymore, actually.

Still, it’ll be interesting to see if any slaughtered goats show up on Miller’s doorstep over the next few weeks. If that’s the case, we only hope the animals get slaughtered humanely.

You know, like under the supervision of a licensed veterinarian or something.
