Last weekend, photags captured Sienna Miller acting naughty.  She was photographed completely nude on a boat along the Amalfi coast in Italy kissing the married father-of-four Balthazar Getty, oil heir and Brothers & Sisters actor.

That’s just about as scandalous as it gets.  Married WITH children.  Boy, Sienna, do you know how to pick ‘em.

But now, an ‘insider’ is claiming that Sienna is not the homewrecker the media is painting her to be.  I think that if I looked up the definition of ‘homewrecker’ her picture would come up.  Maybe even that very picture above.  Seriously.

The friend source says that Sienna’s new man and his soon-to-be ex, Rosetta Millington, were over even before Miller came along.

The pal also claims,”It’s been over with him and his wife for some time.  I believe he’ll be making an announcement shortly.”

Uh huh.  I highly doubt his marriage was on the rocks until Sienna came into the picture (in this case, naked on a boat).  What it sounds like to me is that they got caught and now have to come out with their relationship.

Could this be Sienna acting out; trying to be the one that is doing the two-timing?  We all remember when her ex Jude Law cheated on her with his children’s nanny.  So now she wants to be the bad one?!
And to make matters more scandalicious, Miller’s ex Matthew Rhys (who is also Getty’s co-star) introduced the two!!

This is just a tangled web of Hollywood love, isn’t it?  What do you think, has she been mislabeled as a homewrecker?  Or does she bring houses down as fast as the Big Bad Wolf?
