Ashlee Simpson's (search) Orange Bowl (search) halftime performance was a lemon, according to the 72,000-plus Miami crowd. The 20-year-old singer was soured by a discernible chorus of boos from the audience following a performance of her song "La La."

"You make me wanna scream," she sang before the audience jeered.

Simpson was the finale in a trio of halftime performances, following original "American Idol" winner Kelly Clarkson and country singer Trace Atkins. The camera cut away from Simpson's face once the booing — or perhaps one of Simpson's "hoe-down" dances — began.

The negative vocal reaction comes months after Simpson's boo-boo last fall during a live performance on NBC's "Saturday Night Live," which revealed she used background vocal tracks. The mishap was later attributed to acid reflux.

But the Walt Disney Co. gave the crowd a reason to cheer, dispensing a theme park ticket to every fan in attendance. The giveaway, a promotion that could cost as much as $4.3 million if all the tickets are used, is in honor of the 50th anniversary of its Disneyland park in California.

The second season of Simpson's unscripted MTV reality show, "The Ashlee Simpson Show," premieres Jan. 26 and will capture the "SNL" appearance and preparation for her first nationwide tour, which begins Feb. 18 at Los Angeles' Universal Amphitheatre.
