Whitney Houston once got intimate with Michael Jackson's pet monkey Bubbles

IF you’re of a nervous disposition . . . don’t read on!

David Gest, in his Michael Jackson documentary, to premiere in the UK on October 24, recalls when the late star’s monkey ­Bubbles got up close and personal with Whitney ­Houston.

He reveals: “Whitney was having dinner with Michael at his Neverland home when she accidentally dropped her knife under the table. While Michael was retrieving it for her, Whitney felt her toes being sucked. She moaned, ‘Michael, is that you? Don’t stop. That’s so sensual’. Yet Michael’s head popped up and her toes were still being sucked. It turned out it was Bubbles.”

Houston herself was interviewed by Gest for his upcoming documentary on the King of Pop . . . though it's unclear whether she is the source of such a "toe-curling" story or not.

Gest previously told the British tabloid, The Sun, that Jackson's "all-time favorite vocalist was Whitney Houston. Michael always said she could sing the Yellow Pages and it would sound great."
