Katherine Heigl thinks her children are "far more creative" after she limited their phone usage.

The former 'Grey's Anatomy' star and her husband Josh Kelley - who have kids Naleigh, 15, Adalaine, 13, and eight-year-old Joshua together - have noticed the benefits of their daughters not being allowed their smartphones for half the week.

Katherine told E! News: "Naleigh has started baking and cooking a lot because I now I have a rule about the phone: They don't get it three days a week and they only get it after school. "Adelaide, she talks about wanting to be an actress."

She has also noticed an improvement in the relationships between her children as a result of the rules.

She added: "[Adalaine] and her brother have been starting to play music together.

"Adelaide is playing the electric guitar, Joshua's playing the drums--and they're actually really good.

"It's really kind of beautiful to watch them do this together, and watch them be excited and interested in something other than their devices and their phones."

The 46-year-old actress wanted to "mitigate" the amount of time her kids are spending online and encourage them to find other ways to stay entertained.

However, Katherine pointed out that it wouldn't be reasonable to totally removed their phones from their lives.

She explained: "Modern moms have to really deal with that in a way that our mothers did not.

"I have always felt like I can't take it away completely, because then they aren't really in the world.

"All their friends are on it and all their the schoolwork is on it."

Meanwhile, Katherine previously admitted while at one point she "for sure" wanted to expand her family, the COVID-19 pandemic "really clarified" the decision that she and Josh were satisfied with three kids.

In 2023, she told E! News: "Three is enough, and I don't think I can spread myself any thinner in this arena."
