2006 may finally be Ashlee Simpson’s year — and what a difference a year can make. The last two times Simpson came to Tucson, she performed at a bowling alley and at a high school. When Simpson stops in Tucson Sunday, she’ll be playing for thousands at a benefit concert at the Tucson Arena. Though originally she was known as the little sister of pop/reality TV star Jessica Simpson, Ashlee Simpson began making a name for herself in 2002 as an actress on the WB’s “7th Heaven.” By 2004 she had her own MTV reality show, “The Ashlee Simpson Show,” which was a nice introduction for her debut album. The new pop star stepped out of her wholesome sister’s shadow and presented herself as a raven-haired punk rocker on 2004’s “Autobiography.” The platinum-selling album, which she co-penned, hit No. 1 and was a commercial — and even occasionally a critical — success. “All in all, it’s an unexpectedly strong debut from an artist who seemed destined to be a footnote to her famous older sister, but just may wind up with a more interesting career,” said the All Music Guide. With the highs came the lows. October 2004 saw Simpson caught in the act of lip-syncing during a “Saturday Night Live” performance. “I felt pretty low,” she says in this month’s Cosmopolitan. “People were really mean, so I chose not to watch all those shows that were being so rude about me.

That was the cool thing about it.” And pick herself up she did. Read more.
