Kesha is dropping her sexual assault lawsuit against Dr. Luke.

The Warrior singer has been fighting a contentious legal battle in California against her former music producer for nearly four years, during which time she's been locked in a contract with Dr. Luke and his Kemosabe record label, which is under the auspices of Sony Music.

On Monday, it was announced that Kesha has dropped the California suit in an effort to focus on creating new music, according to her legal counsel. However, she is maintaining her lawsuit against Dr. Luke in New York.

"Kesha has dismissed her California action without prejudice while she pursues her appeal and other legal claims in the New York courts," Daniel Petrocelli, a member of Kesha's legal team, explained in a statement to ET.

"Kesha is focused on getting back to work and has delivered 28 new songs to the record label," Petrocelli continued. "We have conveyed to Sony Music and the label Kesha’s strong desire to release the single and an album as soon as possible."

Kesha later addressed the news on Twitter, sharing, "My fight continues. I need to get my music out. I am continuing to fight for my rights in New York. Thank you for all your support."

Kesha has released no new music in over four years, as she's tried to get out of the multi-album recording deal. The 29-year-old singer has previously argued that she couldn't work with a man she claims sexually assaulted and drugged her.

Dr. Luke and his legal team have denied the allegations throughout the court battle, and have not yet addressed this latest development. ET has reached out to the producer's rep for comment.
