Now, she is taking a break from the group and spreading her creative wings with a new solo album called "Dangerously in Love."
"Basically I wanted to do an album that was timeless," Knowles says on The Early Show. "I wanted to write and produce and sing an album that would never go out of style and that would have classic music that's good quality music and, hopefully, bring something different to my generation. We have all the great artists that maybe some people may not have heard. I just want to introduce that music to these wonderful young people."
For her solo album, Knowles mixes hip-hop, rock and jazz with help of such artists as: Missy Elliot, Jay-Z, Sean Paul, Mark Batson, Mario Winans, D-Roy and Mr. B, OutKast's Big Boi, Rich Harrison, Fanatic, Scott Storch and Luther Vandross.
As part of the Summer Concert series, Knowles performed her new single, "Crazy in Love" adding some heat to an already sweltering day in New York City.
"Crazy in Love" features rapper Jay-Z. "It's always wonderful working with him," Knowles says. "We have a wonderful vibe in the studio. We compliment each other." And it is a top-10 single on the Hot 100 on Nielsen SoundScan.
Her album's first-week performance has also been impressive, selling 317,000 copies in the United States. Some of the songs she wrote for it are autobiographical in a way, Knowles says, "I write my songs from personal experience, as well as things that I experience from my friends. Nobody wants to tell me anything about their personal life when I'm writing an album because everything they say ends up in a song."
The 21-year-old Houston native is a founding member and songwriter for the multi-platinum-selling group Destiny's Child. Knowles says, "We just finished performing together. We will always perform together as long as we're friends. We definitely are. And we will be back in the studio next summer."
Fans of the group were first introduced to the young voices of Destiny's Child in 1997 with their multi-platinum single, "No, No, No," from their self-titled album.
The young ladies' second album, "The Writing's On The Wall," sold more than 10 million copies worldwide. It was propelled by hit singles such as "Jumpin, Jumpin," "Say My Name" and "Bills, Bills, Bills."
In 2001, Knowles won the ASCAP Pop Songwriter of the Year Award. She was the first African-American woman and the second woman ever to receive that honor.
In addition to music, Knowles also acts. She will star with Cuba Gooding Jr. in "The Fighting Temptations," due out in September. This is her first film since her turn as the high-flying Foxxy Cleopatra in last year's "Austin Powers in Goldmember."
Knowles says, "Hopefully, every year I'll do another film."
