The single is not out yet, but will be released on Oct. 9. "Second Hand Heart" will serve as the lead single off Haenow's debut album, out Nov. 13.
"I fell in love with 'Second Hand Heart' with the first listen," Clarkson said in a press release announcing the collaboration. "Lyrically and musically, it is right up my alley."
Now, for some bad news: Just weeks after canceling a string of U.S. tour dates to rest her voice, Clarkson says that doctors have instructed her to nix all upcoming dates in Canada and the U.K., as well.
"I am truly sorry that I have to cancel the remainder of my tour dates," Clarkson wrote on her website. "Unfortunately my doctor is telling me I have to stay on vocal rest, but I am working hard to get better as fast as possible."
A post on her site states that all tickets can be refunded at the original point of purchase.
During her Piece by Piece tour stop in Los Angeles last month, Clarkson let it slip that she's expecting baby No. 2 with hubby Brandon Blackstock.
"I was not planning on announcing this. I'm totally pregnant again," Kelly admitted, after breaking down in tears while singing "Piece by Piece." The revelation elicited a loud cheer from the audience and prompted the singer to take a bow.
After Kelly shared the news, she told the crowd, "That was not planned. I just didn't want you to think I was crazy. Honestly I'm just hormonal today. Nothing's wrong. I'm okay. I haven't vomited yet!”
The 33-year-old singer also revealed that she and her husband had not yet told some of their family about the good news.
"I'm kind of afraid to talk to my husband after this," Kelly added, jokingly.
