Kelly Rowland caught fans up to speed on the pure interaction caught between her and JAY-Z on Wednesday, Oct. 13.

The "Dirty Laundry" singer was on Instagram Live when she revealed that the moment wasn't as much of a big deal to her as it was to fans, Billboard reports.

“Some things I will never understand,” she said.  “Like, I see my big bro all the time, but I guess you guys never see what we see? I don’t know.”

Her response didn't stop fans from still swooning over the moment, though.

"He gave her that look like 'I [thought] you said you wasn't gonna be able to make it,'" one fan commented. 

Another person commented they were simply just shocked at JAY-Z expressing some sort of emotion.

"That's right Kelly we've never seen him publicly show this much emotion," they said.

Another person added how "sweet" the close familial relationship between the two is.

The two were at the movie premiere for Netflix's The Harder They Fall, which was produced by the music mogul himself, as Blavity previously reported. JAY-Z also contributed to the movie's soundtrack, which has yet to be released.

In the short clip, JAY-Z looked back over his shoulder shocked that he somehow overlooked Rowland, and the two embraced one another in a genuine hug.

While walking off together, JAY-Z appears to tell his wife's former bandmate, "I didn't even know you were here."

Rowland has been embraced as family by Beyoncé and her loved ones. In a 2015 letter penned by the "Check on It" singer's mom, Tina Knowles Lawson writes of her relationship with Rowland, Beyoncé, Solange and their cousin Angie Beyince, saying she "gave birth to two of you, but I have four incredible daughters."

She later adds that Rowland is "a true gift from God and "the sweetest, most kind person I had ever met." She also reflected on Rowland coming to live with them when she was only 11 years old.

"You are also a true survivor. You never give up. Your discipline and drive always inspires me. You make me want to take better care of my body and constantly motivate me to exercise and take time for myself," she said of the mom of two.

Knowles Lawson continues to describe the close relationship she has with the women.

"When I’m feeling sad or not-so-cute or maybe a little sorry for myself, and you all include me in your group chat and tell me how hot I still look or how cool I am. Maybe you send me a crazy YouTube video. What actually works best is a cute photo of my grandchildren," she wrote.

"I remember slumber parties after my divorce, when we watched old movies and ate a lot of ice cream. I felt so loved and supported. The roles were reversed, and it was ME who needed nurturing," she continued.
