If you've been on the Internet or on Twitter, or if you watched Grammy Awards, you know about the death of Whitney Houston.
The pop superstar was found dead on Saturday.
Officials are trying to figure out what caused Houston's death.
Whitney Houston was a musical icon.
The singer launched a career in the 1980s.
She sold more than 170 million albums and won six Grammy Awards, and her success extended to movies, too.
In recent years, Houston made headlines because of her battles with drug addiction.
She was 48 years old.
