Dennis Rodman keeps his valuables close when he flies. A passenger on the former NBA star’s flight from North Carolina to Fort Lauderdale noticed him obsessively counting $100 bills stuffed in a carry-on bag. “He was nervously chewing on a red straw,” our spy adds. “He must have had four or five grand in there.” Asked what the cash was for, Rodman’s rep told Page Six it was left over from partying after a deejay gig in Pennsylvania. “He was counting it because he thought he had been robbed, but it turns out his business manager was holding onto the rest,” his rep explained. Seated next to Rodman on the flight was teen equestrian champ Daniela Stransky.
