Hunt was charged with assault with a deadly weapon, police said.
The actress, 28, is best known for her work on the daytime dramas "Guiding Light" and "One Life to Live."
TMZ said she was arrested Friday night after she allegedly threw a glass at someone's face at Pearl's Liquor Bar in West Hollywood.
The unidentified victim required medical attention but the extent of her injuries was unclear, the celebrity news website said.
The actress was released Saturday morning after she posted bail.
Hunt's lawyer, Shepard Kopp, told TMZ the other woman was the aggressor and Hunt was acting in self-defense.
