Atlanta police say they were called to the Biltmore Hotel on March 27, where Moore told an officer Williams assaulted her.
Police say Moore told the officer she was unable to fill out a statement at that time because she had to be on the set for filming.
An arrest warrant was later issued.
Fulton County sheriff's spokeswoman Tracy Flanagan says Williams turned herself into the Fulton County Jail on Wednesday evening and was released that night. She's charged with simple battery, a misdemeanor. It wasn't known whether Williams has an attorney.
Williams is the ex-wife of former NFL standout Kordell Stewart.
