A world-famous violinist who is being sued by his porn star ex-girlfriend claims in a counter-suit she is a gold-digging extortionist after she accused him of forcing her to drink his urine.
David Garrett, who is a Julliard-trained violinist, is being sued for million by his ex, 28-year-old Ashley Youdan.
The brunette who works under the name Kendall Karson, claims in her civil court filing that Garrett, 35, forced her into rough sex that caused her to break a rib, wanted to hire a sex slave, had sex with transsexuals and used cocaine.
Garrett met Youdan through The Luxury Companion, a Los Angeles escort service, in 2014, according to his counter-suit that was filed in a Manhattan court.

'Karson's seduction of Garrett began with the highly provocative language used to advertise her services as well as her own posts to her social media feeds of sexually graphic messages and photos,' according to court papers.
The world famous violinist became 'enamored,' and Youdan started calling herself his fiancée despite his claim there was never a formal proposal for marriage.
In her suit, Youdan claims Garrett asked her to marry him just days after paying her for sex.
Garrett allowed Youdan to live in his pricey Manhattan loft and also paid her a ,000 monthly stipend.
He reportedly did so in hopes that she would quit the porn industry and become a real-estate agent.
'In reality, Karson used Garrett's money to finance regular parties filled with her friends from the sex-trade . . . in his absence,' Garrett said in court papers.
The filing states that Youdan 'bilked Garrett out of hundreds of thousands of dollars by convincing him that she loved him and would leave her former life [for] him.'
His counter-suit also alleges that Youdan continued to strip and appear in pornographic and erotic films.
'When Garrett discovered the lies and decided to end the relationship Karson shifted from seduction to extortion,' the court papers state.
The couple broke up in March 2015 and she allegedly demanded 0,000 for her silence.
Garrett's lawsuit says he paid her ,000 first, but she then increased the demand to million.
He alleges that when he refused her demands for money, she filed her lawsuit claiming that Garrett forced her to drink his urine and hire a sex slave.
Youdan (above) also claims in her civil suit that he wanted to hire a sex slave, had sex with transsexuals and used cocaine. In court papers recently filed, Garrett called her claims 'scandalous allegations' that are false

In court papers, Garrett called her claims 'scandalous allegations' that are false.
However, he admits in court papers that Youdan 'threatened to reveal private confidential information.'
Youdan claims in her suit that while they lived together, on Christmas Garrett allegedly tried to hire a sex slave.
'After seeing an advertisement for a 'sex slave' on the Web site Craigslist, [Garrett] responded to the advertisement hoping to perform 'BDSM' acts on the 'sex slave' and place the 'sex slave' in a cage while [he] and [Youdan] attended a nightclub,' Youdan claims in court papers.
The sex slave never showed up though according to Youdan, despite Garrett waiting outside his apartment for the woman.
Two weeks after this, on January 7, 2015, is when Youdan claims that Garrett forced her to drink his urine.
She alleges in court papers that the two were having sex on the kitchen counter when '[Garrett] left [Youdan] to urinate in a glass.'
Youdan goes on to claim in her lawsuit that Garrett 'negligently and recklessly held [her] down on the kitchen counter by her neck and threw urine on [her] face ... [Garrett] then pressed down on [her] throat so that she would have to swallow any urine in her mouth.'
She also claims that Garrett threw urine 'between [her] legs, some of which entered into [her] vaginal cavity causing serious injury. [Garrett] then proceeded to engage in intercourse with [her] despite her objections.'

Two weeks after trying to hire a sex slave, Youdan claims Garrett forced her to drink his urine, and in October broke her rib during rough sex (leg bruise allegedly from Garrett stealing her phone in January, alleged broken rib on right)
Youdan claims after this she had to go on antibiotics and believes the incident later caused her to develop kidney stones, which she is still dealing with.
Youdan claims that the relationship between the pair became further strained in October 2015 when she 'learned about sexual relationships [Garrett] had engaged in with transsexual pornography actors and escorts.'
She said that later that month she was dancing in Long island and refused to let him in the club.
Youdan claims she then arrived home to find Garrett 'extremely intoxicated and high on cocaine.'
That is when shew claims Garrett forced her to have intercourse despite her objections, 'slamming [her] body against the kitchen counter over and over, consequently bruising and fracturing [her] rubs.'
Youdan said she was forced to hide her relationship from Garrett after that point at the request of his management, but that he did present her with an engagement ring on December 23 to confirm they would be getting married in the future.
She claims he grew enraged however in late January after she posted a photo of the ring on social media and 'angrily broke into the bathroom, breaking the door handle and lock, to take [her] cellular phone from her so that he could delete the social media posts.'
Youdan wrote in court papers that he slammed her to the ground while trying to get her phone, bruising her leg.
Garrett then refused to let her leave the apartment Youdan claims, and when she did escape caught up with her and convinced her to return to the apartment.
Garrett, who was born in Germany, has released 18 albums and starred in the 2013 film The Devil's Violinist alongside Joely Richardson.
