Kesha took to the streets of LA for a bike ride on Tuesday and proved her multitasking abilities by chatting away on her cell phone as she rode.

The Tik Tok hitmaker wore a bright pink Budweiser hoodie and black sweatpants for her ride around.

Her long blonde hair was tied up into a messy ponytail and the 29-year-old rocked a pair of aviator shades.

It came as it was revealed that producer Dr. Luke has filed documents requesting a judge to add a defamation claim in his lawsuit against Kesha after his team discovered she texted Lady Gaga claiming he raped another artist. 

The legal drama between the two has been going on for more than two years since Kesha filed suit in October 2014 alleging Dr. Luke sexually assaulted her.

He denied the claim and fired back with his own defamation suit.

Legal woes: No doubt the exercise served as a distraction from the news Dr. Luke is adding a defamation suit to his ongoing lawsuit against the 29-year-old over texts she sent to Lady Gaga

In documents obtained by DailyMail.com, Dr. Luke claims Kesha is on a 'malicious campaign to destroy' his reputation and career. 

While the texts in question do not specifically name Dr. Luke, he believes the insinuation to be clear.

Kesha has retaliated by filing her own documents, claiming Dr. Luke is seeking revenge against her and has not allowed her to release new music. 

Her lawyers claim that Dr. Luke 'verbally abused and physically threatened Kesha during the parties' contractual relationship', failed to allow Kesha to return to work and release new music, and maintained 'absolute and complete control over every material decision facing Kesha's career despite leading the Court to believe that she would be allowed to work without Dr. Luke's 'involvement'.'

In early January, a 'mysterious message' from April 2016 that Kesha sent to Lady Gaga was added to evidence as part of Kesha and Dr Luke's ongoing legal battle

Her counterclaim also says Dr. Luke has admitted to withholding royalties and royalty statements that were due and owing for over two years.

Dr. Luke, she says, is trying to punish and coerce her for speaking up.

But In a statement to DailyMail.com, Dr. Luke's lawyer, Christine Lepera, said: 'Dr. Luke seeks to add an additional defamation claim against Kesha based upon the discovery of another false and defamatory statement she made about him that was part of her calculated effort to harm his reputation and business. 

'Kesha's new proposed counterclaim simply repeats the meritless and untrue allegations that were set forth in her earlier pleadings and which Dr. Luke fully disputes.' 

He is still claiming that Kesha and her mother have engaged in a 'smear campaign,' and that the artist won't fulfill her obligations under contracts, but he's now adding that since the preliminary injunction motion, Kesha's team has 'embarked on a conscious and coordinated effort to 'blacklist' him from the music industry. 

At the beginning of January, DailyMail.com reported that Lady Gaga and Katy Perry were been dragged into the ongoing legal battle between Kesha and her former music producer Dr. Luke stemming from her accusations of sexual assault.

A text message from April 2016 that Kesha sent to Lady Gaga was added to evidence, and a judge gave Dr. Luke - whose real name is Lukasz Gottwald - the green light to show the message to the Poker Face singer and pop star Katy Perry.

The evidence was presented as part of a hearing on December 26 in New York, when both parties worked to hash out an agreement on discovery, deciding which documents and records they will exchange with one another.

At that point, the contents of the text message from Kesha to Lady Gaga were unknown and sealed by a judge.

Dr. Luke sued Kesha's lawyer in 2014 after the lawyer claimed on social media that the music producer raped Lady Gaga. 

Both Dr. Luke and Lady Gaga denied the allegation.

Gaga did, however, speak out in support of Kesha. She said: 'I feel like she's being very publicly shamed for something that happens in the music industry all the time, to women and men.

'I just want to stand by her side because I can't watch another woman that went through what I've been through suffer.'

Perry has not publicly commented on the Dr. Luke/Kesha legal battle and it is unknown why Dr. Luke was given permission to show her the text message.

Since October 2014, Kesha has been tied up in a legal battle with Dr. Luke, who is also the founder of her label, Kemosabe, in which she alleged that he sexually assaulted her - a claim he denied and fired back with his own defamation suit.

In a civil suit in California, she claimed that among other abuse, he once raped her, and he retaliated by suing her and her mother, Pebe Sebert, in New York for defamation and breach of contract.

Kesha's attempt to get a preliminary injunction against Dr. Luke and Sony Music failed last February. In an appeal, her legal team insisted her having to work for Sony was comparable to 'slavery.'

In April, however, a judge at the New York State Supreme Court dismissed Kesha's counterclaims against Dr. Luke for employment discrimination, gender-based hate crime and infliction of emotional distress.

Sony Music have furnished her with a list of producers she can collaborate with other than Dr. Luke, who has denied her accusations of wrongdoing.

In August, she dropped the case in the California court system, but the legal battle in New York is still ongoing.

Kesha is appealing two rulings in New York that prevented her from breaking her contract with Dr. Luke's label and that dismissed her claims of sexual and emotional abuse.

Kesha hasn't released an LP for Kemosabe since the 2012 album Warrior, nor an EP since the 2013 record Deconstructed. She did, however, drop a single called True Colors (with Zedd) this April.

Near the end of November, Sony revealed that new Kesha work is on its way to the public, telling Buzzfeed News: 'We hope to share exciting new music with Kesha's fans soon.'

During the discovery conference on December 26, a judge heard both parties argue their points prior to a New York Trial.

The court order shows that Kesha will not have to produce certain emails, but has agreed to turn over drafts of her original complaint against Dr. Luke.

As for the text message from Kesha to Lady Gaga, a judge ruled that Dr. Luke 'may share with Lady Gaga and Perry the April 2016 text that Kesha sent to Lady Gaga, which Kesha turned over in discovery.'

Many of Perry's songs, including Roar, California Gurls and I Kissed a Girl, were produced by Dr. Luke.

As recently as this past summer, Dr Luke helped Perry secure a deal with NBC to use her song Rise during the 2016 Summer Olympics in Rio de Janeiro, according to Celebuzz.com.

Kesha's career has been in limbo since she first sued Dr. Luke in October 2014, alleging his abuse caused her to develop a severe eating disorder that required her to enter rehab.

In May she delivered a standout performance of Bob Dylan's 'It Ain't Me, Babe' at the Billboard Music Awards, but was only permitted to do so after Dr. Luke's label withdrew objections to her appearance because they feared she would use it as a platform to attack the producer.

Dr. Luke has never been charged with any crime and has vehemently denied he abused the singer.

Court documents seen exclusively by Daily Mail Online, filed in October 2014, chronicle a decade of abuse and exploitation so complete that it left Kesha 'broken, damaged and traumatized.'

She 'lived in a prison of abuse, suffering a psychological and physical fallout so severe as to be described as 'life-threatening', requiring her to check into rehab.

He has sued the singer for defamation, and that case is still pending. Her former lawyers said she was too afraid of him to speak up at the time.

Dr Luke has produced some of the biggest pop hits of the past decade, working with stars including Miley Cyrus, Kelly Clarkson and Nicki Minaj.
