AS VEGAS - Lauren Nelson, an aspiring Broadway star, was crowned Miss America on Monday night, the second year in a row that a Miss Oklahoma has won the crown.

Nelson, 20, of Lawton, Okla., is a student at the University of Central Oklahoma and wants to get her master's degree in musical theater.

Shilah Phillips, the first black Miss Texas, was first runner-up, and Miss Georgia, Amanda Kozak, was second runner-up. Viewers voted Miss Alabama, Melinda Toole, as Miss Congeniality.

Nelson was crowned by last year's winner, Jennifer Berry. Nelson, a blonde who told judges she wishes she was taller, sang "You'll Be In My Heart" in the talent competition and plans to promote protecting children online during her yearlong reign as Miss America.

She gets a $50,000 scholarship with the crown and stands to make thousands more in appearance fees.

The pageant tossed in a few reality-TV twists on the way toward selecting its ideal woman in a new time slot on the Las Vegas Strip.

Mario Lopez, of "Dancing with the Stars" and "Saved by the Bell," hosted the show, its second year at the Aladdin Resort & Casino on the Las Vegas Strip. The pageant moved from Atlantic City, N.J., last year in an attempt breathe new life into an institution that had fallen far from the forefront of American pop culture.

Although previous experiments with reality gimmicks fell flat, this year's show included viewer voting and increased participation from the panel of celebrity judges, which included MSNBC talk show host Chris Matthews.

"We embrace Miss America for what is it, but we're taking what's been done before and giving that a turn," executive producer Charlie Haykel, of Mischer Productions, the company also producing next week's Super Bowl halftime show.

The changes are part of a larger marketing blitz aimed at reintroducing a new generation to Miss America, a feminine idol born of a publicity stunt on the New Jersey seaside in 1921.

After a long reign as a cultural icon, Miss America's ratings have plummeted, and sexier reality shows have eclipsed her girl-next-door appeal. The addition of pop quizzes and casual-wear contests couldn't save the pageant from losing its network TV contract in 2004.

MTV-Networks' CMT picked it up in 2005 and has been attempting to restore the old girl to her former glory. It stripped the pageant of the failed gimmicks, and for the first time in decades brought back Miss Congeniality.

The 2006 live crowning of Berry attracted less than a third of the viewers it had the year before, but was replayed 20 times on CMT and its sister-network VH1 for a total of 36 million viewers.

With a year to market its new product, CMT came back with its own set of gimmicks - a Bert Parks ringtone, a $1 million giveaway for picking the winner and a reality-TV special intended to help viewers connect with the contestants in the days before the crowning.

Producers took cues from "American Idol" and incorporated interviews with judges and text-message voting after the swimsuit, talent and evening-gown competitions.

They also moved the show off a date night. CMT, which reaches 83 million households, hoped the Monday-night airing would attract a broader, younger audience - the sort of viewers whose devotion first catapulted the beauty queen to prominence.
