Beyonce Knowles, Kelly Rowland and Michelle Williams -- collectively known as Destiny's Child -- will reunite in the studio to begin work on their first album of new material together in more than two years, lead singer Knowles tells Reuters.

"Destiny's Child will be back in the studio in January," she says. When last seen in a studio together, the Grammy-winning R&B trio put together "Survivor," their top-selling third album, in 2001.

The three singers went their separate ways later that year in pursuit of solo projects. Knowles, 22, took to the silver screen, with her role as Foxxy Cleopatra in 2002's "Austin Powers in Goldmember" (not to mention the upcoming movie, "The Fighting Temptations," opening Friday). She also scored a hit earlier this year with her solo record, "Dangerously in Love."

Rowland made her solo debut last year with the alternative-sound "Simply Deep," while Williams recorded the gospel "Heart to Yours."

Knowles says she may also release another collection of her own songs before the new Destiny's Child effort, and went on to say that the trio, which started 10 years ago, will also be looking to develop a fresh sound.

"I recorded about 45 songs for my record, but only put 15 on it," Knowles revealed. "I still have a lot of songs that I really love that I couldn't put on the record. So I might be releasing another record of my unreleased songs before the Destiny's Child record comes out."

As for the "new" Destiny's Child: "I want us to work together from the very start on every song because everybody has grown so much," she said. "It's been a couple of years. I know the sound is going to mature and be a little different. We have to figure it out."
