Usher's ex-wife can't afford life support system

London: Singer Usher's ex-wife Tameka Raymond will soon be forced to take off her 11-year-old son Kyle Glover from the life support system as the insurance cover is about to expire.

However, Raymond seems to have not lost hope, and keeps telling her friends that she believes in miracles, even though Glover has been declared brain dead by doctors.

"Raymond can only keep Kyle on life-support as long as her insurance company agrees to pay, otherwise she does not have the funds to cover the enormous hospital bills," reported tmz.com.

Usher has been supportive and has stood by Raymond in the tough times but is not providing financial support or paying medical bills.

Kyle Glover - the child of Usher's ex-wife Tameka Raymond - was struck in the head by a passing jet ski on July 07, 2012, while riding an inner tube on Lake Lanier in Atlanta, Georgia with an unidentified 15-year-old girl.

Both children were airlifted to Children's Healthcare of Atlanta at Egleston after the accident, and Kyle reportedly registered no brain activity.

Apparently a friend of the family, 38-year-old Jeffrey S. Hubbard, was operating the jet ski at the time of the collision.
