Sienna Miller has had the outside of her house vandalised with the word 'slut' in black spray-painted letters.

Pictures of the exterior wall of her London home also reveal an attempt to draw the sign of Satan – despite Sienna’s security lights and burglar alarm.

The Layer Cake star is clearly not making any new fans after she began flaunting her relationship with married actor Balthazar Getty in public.

Sienna insists that her new man had already split from his wife before they became a couple.
