Debbie gave up custody of Prince Michael and Paris after her divorce from Jackson in 1999.

Paris's voice broke as she told the millions watching the Los Angeles memorial concert: 'I just want to say... ever since I was born.... daddy has been the best father you can imagine. And I just want to say I love him so much.'

Her genuine emotion filled the silent Staples Center, which had earlier shook with laughter, sobs and applause as some of the world's biggest artists lined up to perform and pay tribute to Jackson.

Mariah Carey, Jennifer Hudson, Lionel Richie, Stevie Wonder, John Mayer and even Britain's Got Talent runner up Shaheen Jafargholi took it in turns to perform.
