Getting In Tuna

The already ubiquitous Jessica Simpson will become even more so this summer when she headlines an arena/amphitheater tour. Announced this week, the tour includes 24 dates so far, starting June 5 in New Orleans and ending August 1 at the California Mid-State Fair in Paso Robles. The excursion is called the Jessica Simpson Reality Tour, in an acknowledgement that this is the singer's first tour since MTV's reality show ''Newlyweds'' made her and hubby Nick Lachey household names last summer. No word on Lachey's summer plans, or on whether Simpson's backstage concert rider will require caterers to make certain that all tuna cans are clearly labeled ''chicken'' or ''fish.''
