The Diddy and Sienna Miller saga continues, with the latest installment occurring at the already-over hotspot, Crobar.

Apparently, the two hit the so uncool-it's-almost-retro nightclub this past Saturday night, whereupon an overeager snapper took a forbidden picture of Diddy dirty-dancing with Sienna "Not His Wife, Or the Mother Of His 2 New Twins" Miller.

Page Six has learned that a Saturday night clubgoer at Crobar tried to take a photo of Combs and Miller dancing together. A security guard who entered with Diddy's entourage responded by taking the camera from her hand and confiscating the memory card.

"After the girl took the photo, Diddy didn't say or do anything," a witness said. "By the time he was 20 feet away, one of the security guys handed the camera to the bouncer, the bouncer handed it to the girl, and the memory card was gone."

"Diddy obviously doesn't want photos taken of him with Sienna," another source told us.

Joey Morrissey, who runs Crobar's Saturday night parties, confirmed Combs and Miller were there together. "They came in at 2 a.m. with security guards," he said. The two spent the next two hours "hanging out alone upstairs in VIP having drinks."

Natch, there's still no proof that nothing untoward is going on, but we're just hoping Diddy starts thinking more like a daddy and less like an oversexed mediocre rapper.

Update: Now we're hearing that Sienna just told Life Magazine that she “can’t wait” to have kids, explaining “I know I want that because I have way too much love to give." Hmm, too bad we can't think of any not-so-single dads who need a weekend baby-sitter to watch their newborn twins while they hits Crobar with a hard-partying (and extremely single) actress on Saturday nights…
