According to documents obtained by The Blast, both P!nk and Avril filed sworn affidavits in the defamation case Luke filed against Kesha.
Both women of rock, who had each previously worked with Luke in the past, stated that their decisions to stop working with the producer had nothing to do with Kesha.
The "What About Us" singer states, "The reason I have not worked with Dr. Luke since 2006 has nothing to do with Kesha Sebert, her words, or her actions."
Avril's document has the same statement, except her end date with Luke wasn't until 2007.
The support of both stars is important because Luke is accusing Kesha of costing him millions of dollars in work over her claims of sexual assault. He previously said he could have made over $10 million with Katy Perry that he believes he lost because of Kesha's influence.
As we reported, Kesha sent a text message to Lady Gaga alleging Luke had raped Perry. However, Kesha now claims she was not the first one to reveal that information to Gaga, and says someone else had told them both at the same time. She also says Luke is trying to drag out the defamation case and cause her to become bankrupt due to legal fees.
In the most recent document filing, it was also revealed both Kelly Clarkson and Adam Levine were deposed in the case.
The war between the two remains ongoing in what's turning out to be a celeb-packed legal showdown.
