Gilbert Arenas and Javaris Crittenton have a nigga moment.

Seriously, how stupid are these two multimillionaires?

NBA all-star Gilbert Arenas and his Washing ton Wizards teammate Javaris Crittenton drew guns on each other in the team's locker room during a Christmas Eve dispute over a gambling debt, The Post has learned.

League sources say the pistol-packing point guards had heat ers at the ready inside the Verizon Center, the Washington, DC, home of the Wizards -- whose name was changed from the Bullets over gun- violence concerns.

It was the three- time all-star Arenas, 27, who went for his gun first, sources said, draw ing on the 22-year-old Crit tenton, who quickly brandished a firearm as well.
