After singer Usher Raymond won sole custody of his two sons in divorce proceedings, his ex-wife and celebrity stylist, Tameka Foster, took to Twitter to express her disappointment in losing the battle.

"Money can buy many things... But in the end. Truth & goodness will prevail. I must continue to believe this. Stand firm," she wrote. "A woman's loyalty is tested when her man has nothing... A mans loyalty is tested when he has everything! Don't fear the enemy that attacks you... Fear the fake friend that hugs you. There's not much worse." 

The "Confessions" singer, 33, won sole custory of Usher Raymond V, 4, and Naviyd, 3, during a hearing in Georgia on Friday, Aug. 23.

Foster reportedly "begged" her ex-husband to withdraw his petition numerous times. 

"I was like, 'It's ridiculous, are you mad at me? I don't know why. You know your kids are fine. They're happy. They're productive.' ... Maybe I don't do everything perfectly, but I do the best I can," she said.

The ruling comes a month after Foster's son from a previous relationship, 11-year-old Kile Glover, died from a tragic ski accident. It has not be announced how much time she will get to spend with the her two boys in the new custody ruling.

Foster claimed in her filing that Raymond "visited Kile in the hospital only once," prior to his death. She asked him to send a tweet to his fans on Twitter asking him to pray for his stepson and he refused to do so.

She admitted to the judge that after Glover's funeral, she didn't stick to her visitation schedule with the two boys outlined within the co-parenting agreement.

"Of course, there was no provision for visitation regarding the death of a child. I'm sorry I didn't stick with my visit days, but my son passed," she said at an earlier hearing.

Fox Atlanta reported that the singer's attorney stated at a hearing that his ex was an unfit mother.

"We believe the evidence is that Ms Raymond is incapable of being a proper parent to these children.That she does not have the emotional stability or capacity to bond with them, and therefore she is handicapped," it was reported. 

Foster claimed that she is now a successful business owner, but admitted that in the past she stole diapers and wrote a bad check as a single teen mother to provide for her children from a previous relationship.

"Yes, I stole things," Foster said. "I stole diapers before. I've gone in 7-Eleven and stolen diapers out of the store. I admit it. I was 19 years old. I'm not proud of it. I wouldn't do it now."

The couple divorced in 2009 after less than two years of marrigae. They have been attending hearings and giving testimony for several months, and TMZ reported that Foster is planning to appeal the custody decision.
