Kelly Rowland says she felt 'terrible' after she spoiled the gender reveal of Beyoncé's daughter Blue Ivy in 2011: 'That was the worst moment ever'

• Kelly Rowland reflected on her "biggest mistake" on Billy Mann's "Yeah, I F**ked That Up" podcast.

• She said it was accidentally revealing the sex of Beyoncé and Jay-Z's firstborn child, Blue Ivy.

• Rowland referred to the baby as a "she" in an interview, before the couple announced the gender.

Kelly Rowland said that accidentally revealing the gender of Beyoncé and Jay-Z's eldest daughter was her "worst moment ever."

During a recent appearance on Billy Mann's "Yeah, I F**ked That Up" podcast, Rowland was asked about the "biggest mistake" she's ever made and immediately recalled an interview she gave over a decade ago in which she referred to the then-unborn Blue Ivy Carter as a "she," effectively spoiling the couple's gender reveal.

"Oh, my God. When I made a mistake and told the sex of Bey's baby when when she was pregnant with Blue," Rowland said.

"That was the worst moment ever," she said. "The worst moment ever."

According to Billboard, Rowland unintentionally confirmed the baby's sex when she was asked to give her thoughts on the couple's first child in an interview with Bang Showbiz, just a few months after Beyoncé announced she was expecting at the MTV Video Music Awards.

Rowland told the outlet: "I'm so happy for my sister and her husband. They're so happy in this moment right now, as they should be. They've made a little bundle of love, I'm so excited for them."

"I have no idea what I'm going to buy Beyoncé at the baby shower because Jay is going to buy that little girl every single thing possible," she continued. "She won't be spoiled but she will be very well looked after."

The former Destiny's Child singer told Mann that she didn't realize that she had given away Blue's gender until she saw the headlines the next day.

"I was like, 'What are they talking about? I didn't say — Oh my God!'" she recalled her initial reaction to her mistake. "It was bad because it was no one's business."

Rowland added that Beyoncé was naturally "disappointed" when she got wind that her baby's gender had been revealed before she could have a chance to announce it.

"I felt terrible because it was not my news," the "Dilemma" singer continued. "It wasn't my news to share and I didn't mean it like that."

"The 'she' just kind of slipped out. I was, like, 'uh-oh.'"

Despite the slip-up, Rowland and Beyoncé have remained close friends in the 12 years that have passed since the incident. Speaking to Insider in May, Rowland told Entertainment Editor Tufayel Ahmed that she would be down to reunite with Beyoncé and Michelle Williams for a Destiny's Child tour in the future.

"Bey's on tour. Michelle has this amazing podcast and different things she's working on. I have things that I'm working on, and things lined up," said Rowland when asked about a reunion tour. "We'll see what happens. No promises."
