Kelly Clarkson made sure to tell Carrie Underwood she did the right thing in revealing she had three miscarriages before her current pregnancy.

Talking to Entertainment Tonight, the singer, future talk show host and The Voice coach said she emailed Underwood to tell her how important it is to talk about.

“I know you don’t have to, because it’s a hard thing to do, but it makes women that feel inferior — or feel like something’s wrong with them — it makes them feel comfortable and that people go through it," Clarkson explains.

The pop and sometimes-country star spoke prior to the 2018 iHeartRadio Music Festival in Las Vegas. Underwood and Jason Aldean also performed at the event.

“I’m so happy for her,” Clarkson admits, speaking of Underwood's pregnancy. “I didn’t know a lot of the situations that were going on behind the scenes, and I have a lot of friends that have gone through that several times as well."

During an interview with CBS This Morning, Underwood revealed that she suffered miscarriages in early 2017, spring 2017 and again in early 2018. After getting pregnant a fourth time, the "Love Wins" singer worried she’d suffered yet another miscarriage.

"I was like, ‘Why on Earth do I keep getting pregnant if I can’t have a kid?’” Underwood said. "'Like, what is this? Shut the door. Like, do something. Either shut the door or let me have a kid.'"

Doctors would confirm that the baby was fine this time. She announced she was pregnant in August with a video that also outlined her 2019 tour plans, and why she's not doing a live showcase of her 2018 album until next spring.

It’s not clear when Underwood is due, and she has not shared if 3-year-old Isaiah will soon have a baby sister or baby brother.

The 35-year-old’s new Cry Pretty album just debuted at No. 1 on the Billboard 200. It’s her fourth No. 1 album on that chart, giving her the most No. 1s among women in country music. Cry Pretty also had the best first week of sales for a country album in more than three years.
