Lil Jon couldn’t be bothered with the Oscars. The dreadlocked rapper skipped out on watching the show to party with a group of friends Sunday night at Whiskey Blue at the W Midtown, where he threw back Blue Moon beers and shots of Don Julio. After buying most of the bar a round of shots, he ordered pizza from Artichoke on East 14th Street. “All of a sudden a delivery man walked into the bar with eight boxes of large pizza,” a bemused spy said. “Lil Jon walked around the bar handing out slices.”
