Colin Farrell might have secretly gone off and married!  How did this slip by so no one noticed?

More pictures after the jump…

So what finally gave him up?  He was caught in public and trying desperately to hide his left hand – the ring finger hand – so that inspired the press to dig deep.   TMZ got a picture of his hand and surprise!  There looks to be a wedding band on it.  So what gives?  It could be Muireann McDonnell, who he hooked up with a while back.  No confirmation back from anybody if it’s true or not.
