She's Just Cool Like That . . .

I won't go into details, as cool people who mingle with celebs don't tell their good secrets, but let's just say this, Matine slept in "The Dude's" bedroom this week AND played peek-a-boo with "Batman" in the coffee shop.

(he was not this creepy - or sexy - looking drinking coffee and calling Matine a "he")

And she's only 420 days old. I will alert US Weekly next year when The Obama children come to her birthday party on the Moon.
