Whitney Houston 2009 AMA Performance

Whitney Houston continued her comeback campaign at last night's (Nov. 22) American Music Awards. The diva performed her inspirational ballad 'I Didn't Know My Own Strength' off her latest album 'I Look to You,' and was presented with the International Artist Award by actor Samuel L. Jackson. Houston launched her comeback in August when she sat down with Oprah Winfrey for her first interview in seven years. Houston discussed her drug addiction and admitted dysfunctional relationship with ex-husband Bobby Brown in the interview, which was considered one of the most anticipated interviews of the decade.
