Time heals nothing for pugnacious rapper Foxy Brown. The 30-year-old entertainer was busted at 5.40 p.m. today in Brooklyn after a nasty, name-calling run-in with her old nemesis and neighbor Arlene Raymond, sources said.

Brown allegedly snarled at Raymond “What are you looking at — what’s your problem?” sources said. “They were getting into each other’s face,” said one source.

Another source said the B-word got bandied about by the fuming Foxy as the pair squared off at 151 St. Marks in Fort Greene. Neighbors stepped in and held Foxy before any contact was made, according to another source.

Raymond — who has a restraining order against Brown — called cops, and Brown was hauled off to the 77th Precinct for violating the order of protection.

It seems to be a summer thing between Brown and Raymond. The rapper was previously accused of hitting Raymond with her Blackberry on July 30, 2007, when Raymond complained that Brown was playing her car stereo too loud. Brown then ran into Raymond a few days later. “Brown hurled her BlackBerry at her [Raymond], cutting her lip and knocking a tooth loose,” authorities reported at the time.

Brown has been released on $50,000 bail. Chaz Williams, her manager, says the charges are false.
