Julia Louis-Dreyfus and Jason Alexander ended up sore losers in a frustrating game of eenie-MEANIE-miney-mo with ex-boss Jerry Seinfeld! Trouble started when Julia — whose untitled sitcom debuts this fall on NBC — told pals she was certain Jerry would do a guest shot! Julia was stunned when Jerry turned her down flat, saying she’d been beaten to the punch by Jason — who launches his sitcom “Bob Patterson” on ABC this fall. Julia was shocked and extremely upset, but Jerry — for reasons known ONLY to him — felt he couldn’t do both shows! So rather than choose between his ex-co-stars, he decided he wouldn’t commit to either one. “You don’t NEED me!” he told them with that “Seinfeld” whine. Smart money’s betting feisty Julia and Jason will lay heavy guilt trips on Jerry, so . . . stay tuned!
