Poker Hater Joan Rivers Detained at Costa Rica Airport

What was comedian Joan Rivers doing in Costa Rica?  Perhaps looking for some of her online poker friends over at UB.com?  That's the website that is represented by Rivers arch Celebrity Apprentice nemesis Annie Duke and they are based in CR.

While attempting to leave Costa Rica, Ms. Rivers was reportedly detained.

From TMZ.com:

The drama unfolded after an airport official checked out Joan's passport and became suspicious when he noticed it read "Joan Rosenberg AKA Joan Rivers."

Joan claims she tried explaining her late husband's name was Ed Rosenberg -- but the official found the whole thing fishy and gave away her seat on a flight back to Newark. Joan was pissed.

We're told police were called to the scene -- but Joan never got her seat back.

Rivers claims she was forced to put herself up in a hotel overnight to wait for another flight out this morning.

We're told the passport situation was eventually resolved and this morning Joan got on a plane -- but as you could imagine ... she ain't happy about it.

We know she was probably cursing out Annie Duke too.
