When Whitney Houston sang "I Didn’t Know My Own Strength" at 2009's American Music Awards, it was a moment of triumph for newly single women everywhere. In 2006, the R&B star walked out of her disastrous marriage to Bobby Brown, taking teenage daughter Bobbi Kristina with her, and she spent the next 3 years recovering from that emotionally abusive relationship and the drug addiction that had accompanied it. The singer, 46, told Oprah she’s finally learned to love herself: "That's the great part. That's the good feeling." We’re thrilled Houston’s back, Bobby-free and better than ever.
