Chris Brown plans to sue a woman for defamation after she accused him of raping her in a Paris hotel.

The American R&B star was released from prison on Tuesday without charge, after being held for questioning overnight in Paris, following the rape accusations.

The 29-year-old's French lawyer, Raphael Chiche, said Brown vigorously denied the allegations and he is preparing to file the defamation lawsuit on behalf of his client.

Chris Brown is free. No lawsuits were filed against him. He vigorously challenges the charges against him

Chiche said.

'A complaint for slanderous denunciation will be filed tomorrow with the public prosecutor of Paris.'

A 24-year-old French model, who cannot be named for legal reasons, told police that she was raped by Brown and two other men during a drug-fueled party at his hotel a week ago.

The ordeal allegedly happened inside Brown's hotel room at the Mandarin Oriental where suites can cost more than US$21,000 (£19,000) per night.

The woman alleges she was attacked by Brown, his bodyguard and a family friend on January 16.

Brown and the two other men were all released from police custody on Tuesday.

An examining magistrate decided to end the initial period of custody without taking the matter further, but this does not mean that the case is closed, according to French law.

Prosecutors have indicated that they will continue to speak to the alleged victim and to try and gather more evidence.

The Paris prosecutor's office said the investigation is ongoing, while the singer's lawyer said his client 'energetically' proclaimed his innocence.

In a post on Instagram following his release, Brown denied the accusation saying it is 'false', 'disrespectful' and 'against my character and morals.'

In an interview with French Closer magazine, the woman said she met Brown 'through a friend' who works at the Crystal Lounge nightclub on the Champs Elysee.

'This friend asked me what I was doing the next day, and if I would like to meet Chris Brown,' said the woman, who finally met the rapper on January 15.

I said yes and the next day, on Tuesday, I had an appointment at 11.30pm at the Mandarin Oriental hotel to meet the rapper. At the reception of the hotel, I found myself with friends of his and other girls. We went up to his suite to pick him up and we all went to a nightclub called 'The Quay'.

Everything was going well. Around 4am, they decided to go back to the hotel. I wanted to go home, but someone in Chris Brown's entourage took me by the arm and said: 'Come on, we'll have a good evening.'

Leaving the nightclub, there were two Mercedes vans that were full up. So I said, 'There's no place, I'm going home.' Then I was told, 'No, come on!'. And I was put in Chris Brown's car with another girl.'

The group got back to Brown's rooms at the Mandarin Oriental.

The woman told Closer:

Before entering the suite, the bodyguard took all our cell phones. It didn't seem surprising given the artist's notoriety and I didn't worry. Once in the suite, we were offered drinks. There was cocaine and cannabis.

'There were about fifteen girls, friends of Chris Brown. The music was loud, people were coming in and out ... It was a bit chaotic.

Asked if prostitutes were present, the woman said: 'I don't know. There were only very pretty girls.'

'At one point, I went to the bathroom. Chris Brown followed me and took me by the right arm. He made me enter a sort of dressing room. He closed the door.'

Speaking of the alleged rape, the woman said: 'It lasted 25 to 30 minutes. It's still too difficult for me to explain in detail what he did, but it was brutal and violent.
