In case you aren't up to date on your celebrity gossip, Sienna Miller is onto her next relationship, albeit still "rumored" with Balthazar Getty. When I saw the pictures of them together, my first reaction was obviously disappointment (he's married with four kids for crying out loud!) but I have to say my anger was directed more towards Sienna than Balthazar. Of course, it takes two to tango, but since she's the unattached, unfazed part of the equation, it's easier for me to call her the homewrecker than it is him. Unfair — yes, but I don't think I'm alone in feeling this way. When it comes to infidelity, placing blame doesn't make the problems go away yet it's still an automatic response so ladies, tell me, who do you think is to blame in this particular situation?
