Beyonce Working on New Material With Diane Warren

Diane Warren is working with Beyoncé on new material, The Associated Press reports. The songwriter, who wrote "I Was Here" on Beyoncé's latest album, 4, played a few songs for the singer last week in New York, where Beyoncé was in town performing at the United Nations for World Humanitarian Day.

Comparing the collaboration to working with Meryl Streep or Robert De Niro in film, Warren marveled at how natural it felt to work with Beyoncé. "Some people come in my studio and I'm like, 'Oh God,' and you've got to fix them up and it's just hard," she said. "Some of the people that get deals, you just can't understand. But then when you work with a Beyoncé or so sadly Whitney [Houston]. . . it's so beautiful."

Warren – who counts Aerosmith's "I Don't Want to Miss a Thing," Celine Dion's "Because You Love Me," Toni Braxton's "Un-Break My Heart," and Starship's "Nothing's Gonna Stop Us Now" among her songwriting credits – has also been working with Dion, Kylie Minogue, John Legend, Emeli Sande and former Destiny's Child member Kelly Rowland, among others, and has written a song that's "probably going to be Aerosmith's single."
