If Greg Keating is to be believed, his mother was with Coco – in the biblical sense.
Exhibit A: Keating’s mother worked just a few floors away from O’Brien in the early ’90s.
Exhibit B: The two of them look exactly alike. (This of course brings up a second possibility: O’Brien and Keating are both the long-lost sons of former Finnish president Tarja Halonen.)
Good enough for a paternity test? Not quite. Good enough for a chuckle? Certainly.
UPDATE: On Twitter, O’Brien denied the accusation.
