Ciara's kids have leveled up as siblings. 

Nine months after the '1, 2 Step" singer welcomed baby girl Amora Princess with husband Russell Wilson, she shared insight into how her older children have adjusted to the newest addition to their family.

"They're the best," Ciara exclusively told E! News at the bebe x Ciara Collection launch party in New York City Sept. 26. “I don't need any help because I have them." 

She noted how her older trio—Future Zahir, 10, who she shares with ex Future, along with her and the Pittsburgh Steelers quarterback’s kids Sienna Princess, 7, and Win Harrison, 4—are very gentle with their little sister.

"I’m like, 'If y'all can practice the same love y'all give to Amora with each other, that would be great,'" she quipped. "Anybody who has multiple kids knows the love-fight relationship is real. But with Amora, she can have the world. They're the best helpers with her."

Sienna, in particular, has also accepted some major responsibilities as a big sister, including changing diapers. "Sienna is my one," Ciara gushed. "She's on it. The boys are like, 'Ew, diaper!' They go, 'Uh uh!'"

"But they love playing with her," she noted of Future and Win. "They love holding her. They actually fight over her in a sweet way. She is so loved, and she is so ready for the world already."

It was especially comforting to see how much her three eldest cared for Amora as the 38-year-old brought them all on the road while she toured with longtime collaborator Missy Elliott over the summer.

"It was the best experience," she shared. "I couldn't have done it without my family, honestly. We were so lucky Russ got to come to a few dates before football started. I had the time of my life."

"It was the perfect combination of everything happening all in one," the Grammy winner continued. "Being on the stage is literally one of my favorite places to be. Being with my babies and my family is my most favorite place to be. To have their support, and to see their cute faces every day with me, and the little personalities that are developing and evolving every day, it was nonstop fun and entertainment."

Another exciting part of touring for Ciara? Showing off the stylish looks that partly inspired her collaboration with bebe.

"I wanted to make sure that this whole collection really embodied my everyday wardrobe vibes, performing, and when I do red carpets," she explained. "I'm a tomboy, but I do like getting dressed up and a little more dressy. I like tapping into the sensual side every now and then."

And collaborating with the iconic brand that became a staple as she rose to fame was a full-circle moment.

"It feels Y2K nostalgic," she said of the collection. "I was excited about the incredible opportunity to be able to partner and work with a brand so iconic—knowing how much brands like bebe literally shaped my fashion life as a young girl coming up."
