Singer Chris Brown says he is sure he will be vindicated after being accused of threatening a woman with a "deadly weapon".

The 27-year-old musician was arrested last week after beauty queen Baylee Curran accused him of pulling a weapon on her during a row at his home about jewelery.

Brown, however, has maintained he is innocent and cannot wait for "the truth" to be revealed, reported ABC News.

"I cannot wait till the truth comes to light about this incident and this situation. You know, because my character’s been defaced and who I am as a person and (my) integrity.I’m glad all my real supporters know me, and know the truth and see the truth," he said.

Brown is expected to appear in court on September 20.
