Tristan Thompson "freaked out" when Khloe Kardashian wanted to cut their daughter's hair.
The 29-year-old basketball player was so upset at the idea of his former partner giving two-year-old True a trim, he called her brother Rob Kardashian and mother Kris Jenner to ask them to beg her not to do it.
Khloe said: "It was funny, the other day, True is going to be three in April and I wanted to give her her very first trim and when I mean trim I mean not even half an inch. I just wanted to cut some of her baby hairs.
"And I don't think Tristan has ever told me no and he really freaked out by me wanting to cut her hair. It was so crazy to me. He was freaking out, he called my brother for my mother to talk me out of it. He called my mom.
"I didn't know he was that adamant about it until everybody else started calling me. But I didn't do it because I also have to show him, 'OK, if you don't want me to do something that badly, I'm not going to do it.' So it's just I think great communication and trust is the most important thing with raising kids."
The 36-year-old star admitted it's not often Tristan disagrees with her parenting so she will always listen when he does.
Speaking on 'The Kelly Clarkson Show', she said: "Tristan is so great and trusts me as a mom and knows I'm always going to do the right thing for True. So he really doesn't tell me 'no' a lot of the times and I'm grateful for that because I think as moms we sort of think we have the right to know what we're doing with our kids."
Like her siblings, Khloe looks to her own mom Kris and dad Rob Kardashian, as well as her stepfather Caitlyn Jenner, for inspiration on raising children as a partnership when the parents are no longer together.
She said: "My parents were the most perfect example and I was really blessed and fortunate to have that as my example and to see that.
"And even with my stepdad, the integration of all of that and how my dad and my stepdad dealt with one another was really just such a beautiful thing to witness.
"They played golf once a week and I'm sure that wasn't easy for my dad but he did it for us. And so having that really selfless example was awesome for us.
"I think with all of us, whether it be Kourtney and Scott, or Tristan and myself, we definitely try to mirror that and always keep it about the kids. But with Tristan, it's a trust thing.
