LOS ANGELES, May 6 (Reuters) - Michael Jackson's former publicist filed a $44 million lawsuit on Wednesday against the self-styled "King of Pop" for failing to pay her for her services.

Raymone Bain, who represented Jackson during his 2005 trial and acquittal on child sex abuse charges and later managed his business company, filed a breach of contract civil lawsuit against the singer in Washington, D.C.

She said in a statement that she had decided "with deep regret" to sue Jackson, describing him as someone "whom I have greatly admired and respected."

But she added; "Unfortunately, Mr. Jackson has elected not to honor the financial obligations of our contractual relationship, despite my numerous attempts to amicably resolve this matter. I am sincerely disappointed in Mr. Jackson's failure to honor his obligations."

Bain, who trained as a lawyer, saw Jackson through some of the most difficult moments in his career. She became his public voice for much of the lengthy child molestation trial in California, Jackson's subsequent stays in Bahrain and Ireland and the financial difficulties that resulted in the sale of his Neverland Valley ranch in California last year.

In 2006 she was appointed general manager of the Michael Jackson Company, which handles his business affairs.
