Michelle was recently on "Live with Regis and Kelly," an American daytime TV talk show. She was chipper, and no one mentioned Heath. I'm guessing that a) she's being urged to make appearances like this, because she used to say she hated them, and b) she agreed to go on only if they wouldn't bring up Heath. Matilda was briefly mentioned though.
They mostly talked about making the movie Shutter Island.
I saw it because four years ago I programmed my TiVo to pick up anything about her and the rest of the BBM cast and crew. I was surprised to see it this week.
