Must be she finds taking their pictures more than every seven years or so boring, too.
More than likely though, she used this shot because she looked good in it.
After all, it is all about her.
Okay, I thought those kids looked a little small for their stated ages, but I wasn't sure. So it is an old picture after all.
On the bright side, she went out and got the "mommy hairstyle." Oh wait, she's British. Never mind.
