Matt 'n Ben Together Again!

The BFFs reunited for a good cause in Las Vegas Wednesday, a poker tournament benefitting victims of the humanitarian crisis in the Darfur region of Sudan.

And although Matt's good-luck charm, his preggers wife Luciana, was there to cheer him on, Jen was nowhere in sight. But we're sure that's just due to the fact that Jen's tending to their little girl at home (and possibly another one on the way?)

But good cause or not, is it really such a wonderful idea for Ben, who apparently has gotten help for a gambling addiction in the past, to return to the tables?
