Texas entrepreneur named Miss USA

Crystle Stewart, of Missouri City, Texas, runs a party-planning and motivational speaking company, and models professionally. She says she wants to dedicate her life to international philanthropy.

"I want to talk to people about how to set a goal and achieve it," she told The Associated Press after the show. "Because I just achieved my goal."

Stewart edged out first runner-up Leah Laviano of Mississippi and Tiffany Andrade of New Jersey.

Miss USA 2007 Rachel Smith relinquished the crown -- and the posh New York apartment that comes with it -- in a show aired live by NBC with hosts Donny and Marie Osmond from the Planet Hollywood Resort & Casino on the Las Vegas Strip. The network co-owns the parent Miss Universe Organization with Donald Trump.

Smith, a former Miss Tennessee USA, said she was headed to Hollywood.

Stewart was headed for the publicity circuit. She said she was eager to travel and spread her message of self-improvement to young women. She noted she was one of only a handful of black woman crowned Miss USA in the pageant's 57-year history.

Contestants from all 50 states and the District of Columbia have been in Las Vegas for nearly three weeks, rehearsing and hyping the 57th annual pageant. After stints in Baltimore and Los Angeles, organizers billed the new venue as a city beloved by the event's international audience.

The pageant tried to showed off its edge, featuring a grinding live rock performance by the band Finger Eleven, music from Rihanna, and contestants in barely there black bikinis and faux-fur coats.

Donny and Marie kept up a steady stream of sibling banter even while swiftly whittling the field.

Donny Osmond told the losers to "put on a poker face" as he sent them home.

"Or use Botox; then it won't move," Marie quipped.
