Kelly Rowland's son felt "happy and proud" when he saw her perform for the first time

She told People: "First of all, I didn't know what to expect. They sat there watching the show with all my family, cause everybody came out, and it was so beautiful. And the first time I came to the back, Noah said, 'Mommy, you did so good.' And he was so happy and proud.

"But it was interesting, because from my sister's perspective, he sat in her lap and she said, 'You should've seen his face! He was trying to figure out why people were responding, and then he'd see you, and you'd laugh, and then you'd go to dancing, and he was like trying to take it all in. He would be upset, and then he'd be smiling.'

"She was like, 'It was like a race of emotions.' I just thought it was really cool. I wish we would have filmed that."

Kelly also has Titan Jewell, 11, with husband Tim Weatherspoon, and the chart-topping star confirmed that she has no intention of stopping her kids from following in her footsteps.

The singer explained: "You know what? If they want to. If they want to, I'll be right there to support them and to hold their hand."

Meanwhile, Kelly previously revealed that she remains very close to her Destiny's Child bandmates.

The singer observed that "female tribes are crucial to life" and Kelly explained that she remains very supportive of her showbiz pals.

Kelly - who starred in the girl group alongside Beyonce and Michelle Williams - told ELLE: "I hear so many people call it a 'tribe' now and it's very true, you need your tribe.

"So many women say, 'oh my god, I love your relationship with the girls [Destiny's Child]' ... and it's because we all genuinely want to see each other be great and go after things that we're passionate about. And if we feel like one [of us] needs a little push, we do that, whether they're ready for it or not.

"It's about being there and making sure they push themselves. You have to be able to have that honesty, love and admiration for each other. I think that female tribes are crucial to life, to everything."
