NEW YORK - JENNIFER Lopez was named People Magazine's most beautiful woman in the world on Wednesday, capping a career comeback fuelled by her new job on top-rated TV show American Idol.

The 41-year-old New York City-born singer and actress joined former winners Halle Berry, Jennifer Garner and Beyonce Knowles to top People's annual list of the world's most beautiful people.

'It's so crazy. Rarely am I left speechless, but I feel honored,' Lopez told People of their accolade. 'I feel not worthy, you know? I feel happy and proud. Proud that I'm not 25!.'

The Wedding Planner actress, who is married to singer Marc Anthony and took time off to have twins in 2008, has enjoyed a revival in popularity since becoming a judge this year on talent show American Idol.

Her new single, the dance pop hit, On The Floor, has been topping charts around the world, giving Lopez her first Top 10 Billboard single since All I Have in 2003.

Lopez, who was dropped by her record label in 2010 after disappointing sales, releases her first new studio album in four years in May, called Love?.
