Now that all three of the Jonas Brothers are happily married with children, there are some lines that they refuse to cross to preserve their work-life balance.

During an interview with SiriusXM Friday, Kevin revealed that they don't give each other parenting advice or meddle in each other's parenting style.

"We really don't give each other advice about family. It's kind of like an unspoken rule. We just do our own thing; do it your own way," the 35-year-old musician said.

Apparently, this "unspoken rule" just came to be over the years, and it wasn't something that they even actually discussed among themselves.

Nick then explains that this setup works for them, "Well, think about it. The last thing you want to hear from your siblings is how to parent your child."

The Next Generation

According to People magazine, Kevin was the first to head down the family way. He died to knot with Daniella back in 2009, and welcomed two daughters: Alena Rose in 2014 and Valentina Angelina in 2016.

The eldest Jonas bro came next. He and Sophie Turner got married then welcomed a daughter named Willa in 2020 then another daughter in 2022.

Unlike both of his brothers, Joe's daughters are kept relatively out of the limelight. There are no pictures of the pair and they do not post their pictures on social media either.

Meanwhile, the most photographed Jonas baby is Nick and Priyanka's daughter.

Earlier this year, Nick and Priyanka welcomed their first child, Malti Marie. The couple began dating in 2018 and got engaged two months later.

Their wedding was one of the biggest and most lavish events Hollywood has seen in a while. They had two separate ceremonies, to honor Priyanka's culture and religion, as well as a western wedding.

Despite constantly being under the spotlight, the couple emphasizes that they prioritize Malti's privacy.

"I've been really protective of this chapter of my life with my daughter. Because it's not about my life only. It's hers too," the model slash actress said.

Parenting Tips?

Aside from being brothers, they are also essentially co-workers; that's probably another big reason why they refuse to mix their personal life with their professional businesses.

"It's a really healthy thing that we never really spoke about, but I think it's the right thing," Nick continued. "So to all the siblings listening, this is some advice for you."
