Lady Gaga's dramatic Oscars performance hit a strong note with Kesha.

Shortly after Gaga took the stage to perform her Academy Award-nominated song, "Til It Happens to You," following a strong introduction from Vice President Joe Biden, Kesha tweeted out her appreciation for the powerful moment.

"thank u @ladygaga and VP @JoeBiden for bringing attention to sexual assault at the oscars," Kesha tweeted. "it hit very close to my heart for obvious reasons."

Kesha and Gaga have grown close in recent weeks, as the former is currently embroiled in a lawsuit in which she accuses music producer Dr. Luke (real name: Lukasz Gottwald) of drugging and raping her a decade ago. Dr. Luke has denied all wrongdoing.

Dr. Luke responded to Kesha’s comments on Gaga’s performance through his attorney.

"Ms. Sebert, who in sworn videotaped testimony from 2011 stated that she had never been sexually abused or drugged by Dr. Luke, is neither a victim nor the appropriate person to be held up as an example for this important issue," Christine Lepera said in a statement.

Last week, Kesha’s attorney addressed the leaked footage of her 2011 testimony.

"Dr. Luke threatened her and her mother ... only after going to rehab and undergoing intense therapy was Kesha strong enough to stand up to this monster," her attorney, Mark Geragos, told ET.

Earlier this month, a judge denied Kesha's preliminary injunction request to be let out of her contract with Dr. Luke and Sony Music's Kemosabe Records. Throughout the ongoing legal turmoil, Gaga has publicly supported Kesha.

Even on Sunday afternoon, Gaga tweeted a special message to her friend.

"I'll be thinking of u 2nite," she wrote to Kesha. "This is not over we'll stand by u until you are free to live a HAPPY life. Everyone deserves that."

Gaga has been open about her own experience with sexual assault, previously revealing that she was raped at 19 years old. The Hunting Ground, the film for which "Til It Happens to You" was written, focuses on sexual assault and rape crimes on college campuses around the U.S.

On Sunday, Gaga performed the song at a large white piano on a dimly lit stage. Towards the end of the performance, she was joined on-stage by a group of sexual assault survivors with various mantras, including "Not Your Fault," "Unbreakable," and "Survivor," written on their arms. The set garnered a standing ovation and moved audience members including Kate Winslet and Rachel McAdams to tears.

"Despite progress over the last few years, too many women and men on and off campuses are still victims of sexual abuse," Biden said in his remarks. "Tonight, I'm asking you to join millions of Americans including me, President Obama, the thousands of students I've met on college campuses, and the artists here tonight, to take the pledge, a pledge that says I will intervene in situations when consent has not or cannot be given. Let's change the culture!

"We must and we can change the culture so that no abused woman or man like the survivors you will see tonight, ever feel they have to ask themselves, 'What did I do?'" he continued. "They did nothing wrong."

Earlier this year, Gaga dedicated her first-ever Oscar nomination to survivors of sexual assault. See what else she had to say in the player below.
