Whitney Houston's manager was so upset at the superstar's burial on Sunday (19Feb12) she had to treated by paramedics, according to music producer David Gest.
The superstar singer was laid to rest in a private ceremony at Fairview Cemetery in New Jersey a day after a star-studded memorial which was televised for fans.
Houston's close family and friends were in attendance, and Gest reveals the star's manager and sister-in-law Pat Houston needed assistance from medics after she started hyperventilating at the graveside.
Gest tells Britain's The Sun, "The grief was so overwhelming for Whitney's sister-in-law and manager Pat Houston that she started hyperventilating at the graveside and paramedics had to be called to assist her.
"Pat was a brilliant manager and I remember Whitney telling me when we met in Copenhagen last March that Pat really kept her organisation running smoothly.
"Family was important to Whitney and they have always been involved in the daily operations of her organisation. Pat was not only a manager but a best friend, like another sister.
"Whitney told me she could always confide in Pat and nothing was ever leaked to the press."
