Bet you still know all the words.
Cleopatra
The U.K. sister act blew up in 1998 with their album Comin' Atcha! and its hit single, "Cleopatra's Theme." They dropped another album in 2000, then disappeared. Their last performance together was in 2009. Cleo Higgins, the lead singer of the group, went off on her own in 2013. She made it to the semi-finals of the U.K.'s The Voice.
Tweet
I was in middle school when Tweet's "Oops (Oh My)" hit the charts — and I had no idea what the song was about, but I loved it. Today I know what the song is about and I still love it. Tweet's last album was released in 2013, but she hasn't really had a hit since Southern Hummingbird. However, it was recently announced that she would be teaming up with Missy Elliot and Timbaland on an upcoming album.

Blu Cantrell
You know you still know the words to Blu Cantrell's "Hit 'Em Up Style (Oops)". In 2008, Cantrell appeared on NBC's Celebrity Circus, but since then we haven't heard much from her.

Dream
Dream's debut single "He Loves U Not" was everywhere in 2001. The girls were signed to Bad Boy Records and were basically the label's original Danity Kane. Their second song "This Is Me" also did well on the charts before the girls drifted off into pop history. Although their breakup was never officially announced, the band dissolved in 2003.
