Katherine Heigl was sans Ashton Kutcher on the red carpet at the London premiere of her new movie “Killers”.

It’s a good job Ashton stayed at home with Demi, because he would’ve only been upstage by Katherine rather voluminous hairstyle.

I can’t even applaud how smokin’ hot her body looks in her Victoria Beckham Fall 2010 black dress, because I’m in a trance wondering what possessed her stylist to create this 50s housewife bouffant.

It did rain in London all day yesterday so maybe it was the humidity that cause this disaster, either way it totally ruins the look for me.

Hopefully Katherine will get a chance to redeem herself.

Christian Louboutin ‘Lady Page’ heels and a black clutch complete the look.
