She's All That.

This article looks at the rise of Lindsay Lohan to Hollywood star. She acts! She sings! She parties! Lindsay Lohan has Hollywood wrapped around her finger--right next to a new promise ring from Wilmer Valderrama. In just one year, Lohan has evolved from Disney tween queen to A-list leading young lady. Thanks in large part to the critical and box office success of this spring's biting comedy Mean Girls, Lohan has captured the hearts and minds of young moviegoers, studio executives and even Olympic champions; interviewed in late August, swimmer Michael Phelps stated the obvious: "Lindsay Lohan is pretty hot." The actress currently has no fewer than five film projects in development--and hopes to have her debut album out in time for Christmas. She's a savvy businesswoman whose choices--from a wickedly funny turn on Saturday Night Live in May to displaying her Britney-worthy dance skills as host of the MTV Movie Awards in June--have revealed her wide-ranging skills. Her upcoming rock album is an attempt to launch her into triple-threat territory. Says Diane Warren, who penned "I Decide," Lohan's single on the Princess Diaries 2 soundtrack: "I think she's going to be a really successful recording artist. I think it's real."
