WHITNEY WOWS LONDON AUDIENCE WITH SPECTACULAR PERFORMANCE...INCLUDING A DUET WITH DAUGHTER BOBBI KRISTINA.

Whitney Houston pulled a Marilyn Monroe (Monroe had to have the lyrics to the Happy Birthday song taped to a podium during her serenade to President Kennedy) before a recent comeback concert in London when she had the lyrics to her hit songs taped to her dressing room wall for fear of forgetting the words once she began her performance. The singer stepped onto the stage at the Caudwell Children Legends Ball on last Thursday evening (5.08.2008), where she stunned the packed venue with her greatest hits. And Houston, who is set for a career revival with a new album later this year (08), was determined not to make a mistake during the performance. So the When You Believe hitmaker asked for the words to all the songs to be printed out and displayed in her dressing room - so she could memorize them thoroughly before going onstage. A source tells British newspaper the Daily Mirror, "Whitney was really nervous before her set. She didn't make any diva demands, and was polite to everyone. She spent 45 minutes reading the lyrics, mouthing the words and holding her hands as if in prayer." And the hard work paid off as the superstar went on to wow the crowd with a flawless performance.

Afterwards, the singer wowed the audience again when she brought out her 15-year-old daughter Bobbi Kristina to sing a duet with her. Audience members tell People.com Houston "looked and sounded amazing" - and they were stunned when she brought Bobbi Kristina onstage to perform My Love is Your Love together. Just last week, The National Enquirer claimed the teenager was hospitalized in February (2008) after attacking her mother and attempting suicide. The gig is the latest step in Houston's comeback - following a battle with drug addiction and a messy divorce from Bobby Brown. She is working on a new album with former mentor Clive Davis - and Kelly Rowland insists problems in the past shouldn't count against her, telling People.com before the London gig, "People should not judge her. She's done more than prove herself."
