Who is the red-haired mother in the recent Kellogg's Nutri-Grain advert?

The one which begins with a different mother and her kid on a beach - she sends the kid to take a picture with some guy (presumably an Iron Man?) and then the kid is older and wearing a midriff-exposing top, and there are loads of other people around. There's a shot of this fairly good-looking woman with red hair who looked really familiar - my first thought was that she looks like Lauren Lee Smith (The L Word, CSI) but that seemed improbable. Face ring any bells for others? Or just a random look-alike?
