*Usher is still under attack by his ex-wife, even after being hospitalized and slapped with a restraining order.

Tameka Foster is fighting for full custody of their children and now she’s got more ammunition.

According to reports Foster is using everything she can to win, including Usher’s stalker.

In the beginning, she cited Usher’s hectic touring schedule and alleged drug use as reason why the singer should only have visiting right. Now she’s saying the kids are in danger because he has a stalker.

Sources say Darshelle Jones-Rakestraw showed up unannounced to his home while the kids were visiting with their father. Usher lives in a gated community and has a tight knit security team.

Coming this August, Foster is expected to present the court with the new arguments, hoping the judge will see things in her favor.
