Competing in a charity "celebrity" boxing match was a Shore thing for Angelina Pivarnick...until some pre-fight partying led to an unscheduled beatdown. The lesser-known Jersey Shore star was getting ready to fight Kerry Schwartz of Frank the Entertainer in a Basement Affair fame - we assume with plenty of shots - at the Taj Mahal nightclub in Atlantic City when she got into it with a woman at the bar before even stepping into the ring. There are conflicting stories about the catfight, with TMZ reporting that police were called, and Angelina was escorted out. It sounds like the Jersey jerk is hoping to avoid a lawsuit, from what her lawyer tells TMZ: "We believe Angelina is innocent of any allegations and if there is any legal action, we will fight it vigorously." However, Radaronline.com has a different story, with a source close to Angelina saying she got sucker-punched. "Some random girl attacked her in the hallway before the fight," Angelina's friend Andy Stein said. It seems Angelina was ready to settle the score with Schwartz after the two exchanged words back in October over - you guessed it - a guy. The two met up after another celebrity boxing event in which Schwartz competed, and this time, Angelina was ready for the throwdown, telling TMZ, "I started the fight. She's a loser and honestly she's gonna get it. I'll f**k her up." Classy. "Angelina is extremely disappointed," Stein told Radar about the ill-fated boxing match. "She had been waiting a long time for this fight." Sounds like it.
