Add Denzel Washington to the list of celebrities who have been to a Diddy party.
However, the acting legend wasn't happy with what he saw at the soiree.
A source told US Weekly about an incident in 2003 between Diddy and Denzel during a late-night bash.
"Denzel screamed, 'You don't respect anyone,'" the insider recalled. "[Denzel and his wife, Pauletta] had been partying until dawn [with Diddy], and they had seen something and stormed out."
The source wasn't able to reveal what Denzel witnessed, and Washington hasn't commented on the incident.
