Whitney Houston's Top 5 Highs and Lows

April 9, 2010 — -- Whitney Houston's woes: like her verses in "I Will Always Love You," they just go on and on and on.

The latest problem to plague the iconic pop singer: reports that she's reacquainted herself with a past demon that she's dismissed as "ridiculous."

Of course, along with the lows, Houston's had herself a share of legitimate highs, like the aforementioned hit song from her box-office-ruling 1992 film debut, "The Bodyguard." (It's got to be worth something if it inspired the next Susan Boyle.)

Below, check out the 46-year-old singer-cum-survivor's five best and five worst moments in the music industry.

1. Bad news Bobby. One hell after another rained down on Houston's marriage, from 1992 to 2007, to Bobby Brown. Houston spilled the details of their abusive relationship to Oprah Winfrey in 2009. "He spit on me," Houston told Winfrey, describing one of her worst fights with Brown. "He spit on me. He actually spit on me. And my daughter was coming down the stairs and she saw that."

Houston's response to him was equally appalling: ""I took the phone and I hit him over the head with it."

2. Drug downfall. In 2000, airport security guards spotted marijuana in Houston and Brown's bags at a Hawaiian airport. More damaging than the pot possession charges were the rumors they sparked about what drugs Houston might be taking.

3. 'Crack is wack.' Houston cleared up some of that mystery in a 2002 interview with ABC's Diane Sawyer. When asked about the ongoing drug rumors, Houston alluded to having used cocaine, pills and marijuana -- but drew the line at crack in what turned into an infamous rant.

"First of all, let's get one thing straight," she started. "Crack is cheap. I make too much money to ever smoke crack. Let's get that straight. Okay? We don't do crack. We don't do that. Crack is wack."
