Las Vegas ? A 26-year-old entrepreneur from Texas was named Miss USA on Friday, besting 50 other beauty queens for the coveted crown.

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

She 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.
