Tameka Raymond made a brief appearance on Twitter asking followers for continued prayers for her son Kyle Glover (Kile).

Although there has been no official statement from the family about his condition, unnamed sources say that Kile has been declared brain dead by doctors. TMZ is also reporting that Tameka’s insurance company is limiting the amount of time she can keep him on life support.

According to our sources, Tameka can only keep Kyle on life-support as long as her insurance company agrees to pay … otherwise she doesn’t have the funds to cover the enormous hospital bills.

We’re told the insurance company hasn’t set a specific deadline, but they’ve made it clear … they’re only willing to shell out coverage for a couple months … tops.

Our sources say that Usher — who helped raise Kyle for several years — has been incredibly supportive in this difficult time… but has NOT offered to pay for any medical bills. We’re told Tameka does not see him as a viable financial option.
