Debbie Rowe broke down after Paris speech

Debbie Rowe, the biological mother of Michael Jackson's two elder children broke down in tears after watching daughter Paris make a moving speech at the pop icon's public memorial.

The 11-year-old daughter of Jackson fought back tears as she paid tribute to the 'King of Pop' calling him the "best father you could ever imagine".

Rowe, who had refused to be a part of the public memorial broke down after seeing her daughter tear up, reported Sun online.

"It was heartbreaking. However strange her relationship with Jacko, she is still Paris' mum. To watch your child so upset on TV in front of millions of people is more than any mum could stand," said a source close to the former nurse.

Paris made her emotional speech at the star-studded LA Staples Center memorial saying, "Ever since I was born Daddy has been the best father you could ever imagine. And I just want to say I love him so much."

Meanwhile Rowe who has been "intentionally omitted" from Jackson's will, is reportedly planning to contest Jackson's mother Katherine Jackson for the custody of the two elder children of Jackson, Prince Michael,12 and Paris Katherine, 11.

Rowe had given up the parental rights to the two children to Jackson after their divorce in 1999.
