Chris Brown has denied the rape allegations against him with a derogatory Instagram post.

US singer Chris Brown took to Instagram to deny the rape allegation made against him by a French model.

Brown shared an image on Instagram that read “This b*itch lyin'” as well as screenshots from two media outlets reporting on the allegations.

Brown wrote a strongly worded, all caps caption: “I wanna make it perfectly clear … This is false and a whole lot of cap [sic].”

“For my daughter and my family, this is so disrespectful and is against my character and morals.”

His denial comes a day after the French prosecutor’s office said he had been arrested in Paris with two other suspects.

Brown, who is a US citizen, has been released from police custody as authorities were still investigating the case, the French prosecutor’s office added on Tuesday local time.

The arrests were first reported by Closer magazine, which said Brown, his bodyguard and a friend were detained after a 24-year-old woman alleged she was raped at the singer’s suite at the Mandarin Oriental hotel on the night of January 15.

The woman said she had met the men at a Paris nightclub earlier in the evening, according to the magazine.

Many have questioned his “character and morals” in comments on his posts, but fans are also defending the singer.

“His response is really to post a picture saying ‘this bitch lyin’ and then talking about how he respects his daughter too MUCH to do this?” said a Twitter user.

“His choice of words speaks volumes to this character he speaks of… absolute TRASH,” said another.

Brown, 29, pleaded guilty to assaulting Rihanna, then his girlfriend, in 2009, an incident that made headlines around the world when a photo of her bruised face was released.

In 2016, he was arrested in Los Angeles after a woman said he had pointed a gun at her. Brown denied any wrongdoing.

A rape conviction in France can carry a sentence of 15 years.
