Why Does Sienna Miller Look Like Her Baby Daddy’s Mom?

Firstly, I would like to state that I think Sienna Miller is super beautiful and pretty much a style icon at this point but her BF and baby daddy’s homeless teen look is really not becoming for her.

While Tom Sturridge, the actor slash Robert Pattinson BFF is 27, Sienna is only 31, but these photos look like a mom who has travelled into the city from Connecticut to get her raggy son back on track. 

The couple strolled the streets of NYC, leaving their SO FREAKING ADORABLE 8-month-old daughter Marlowe Ottoline Layng (gaaasp) Sturridge home for nappies.

What do you think? Am I a B or does she seriously look like she is going to ground him for flunking math?
