"We're thrilled to announce that multi-platinum selling recording artist and actor Nick Jonas is the new headliner for Pride in the Street," The Delta Foundation of Pittsburgh announced on social media.
The announcement came two days after Azalea backed out as the headliner amid outrage expressed by several groups that support the LGBT community.
"When I heard about the difficult position Pittsburgh Pride was in just days before their event, I knew I had to find a way to help," Nick Jonas said in a statement posted on the Delta Foundation's Facebook page. "I'm excited to do what I can to support the LGBT community in Pittsburgh, and I look forward to seeing you this Saturday as we celebrate together."
Azalea announced Monday that she was canceling her performance after several groups complained about anti-gay comments that she had made in the past.
The rapper, 25, tweeted that she regretted making the comments when she was younger, "because I understand they play a detrimental role in the fight for issues that I do truly believe in."
"This has been a difficult decision as I truly support the event and LGBTIQA communities, however I feel my participation at this point would only serve to further distract from the true purpose of the event," she wrote. "I am a firm believer in equality. Unfortunately in the past as a young person, I used words I should not have. The last thing I want is for something so carelessly said to be interpreted as reflective of my character."
Jonas has been a vocal supporter of the LGBT community, telling Out magazine in 2012, "My thoughts on gay marriage are that everyone has the right to love and be loved, and that's the position I take. My upbringing was faith-based, but [the Jonas Brothers and I] believed you should love all others as you want to be loved, because everyone should be treated equally."
Ironically, Jonas had been scheduled to go on tour with Azalea, but when the tour's schedule changed, he had to drop out. Azalea later canceled the tour.
"Initially, when I was supposed to do the tour with her, it changed to later in the year and I was disappointed," he told ABC News earlier this month. "But I made my own plans and I'm very excited about my own run. I hope at some point for her, she's able to go out and do [a tour]. I'm sure she will."
