The 46-year-old actor - who has Delta, six, and Lincoln, seven, with his wife Kristen Bell - admitted he worries about his kids' friendships and how their peers will react to them having famous parents.

He admitted: "[I fear] kids are going to hang out with them solely 'cause of that or resent them because of that.

"To me, the two options both seem terrible. Either they're going to have fake friends or they're going to have people who hate them for no reason.

"I have a good deal of fear about that."

As a result, the 'CHiPS' actor discourages his children from telling their friends who their parents are and when the girls took part in a 'Frozen', play, he advised them not to tell the rest of the group that their mom Kristen portrays Princess Anna in the Disney movies in case it made them "jealous".

He admitted on his 'Armchair Expert' podcast: "I had to tell my daughter, 'You cannot tell anyone in this thing that your mom is Princess Anna... I know you're proud and you should be able to say that, but I'm just warning you, that'll probably make other kids jealous and they won't know how to handle that feeling.' "

And his podcast guest, Justin Timberlake, admitted he had experienced similar with his five-year-old son Silas because of his role in the 'Trolls' franchise.

He said: "We have this same thing where the kids at school with my five year old are like, 'Your dad is Branch from Trolls.'

"I guess for guys like us, the hope is that we just keep instilling in them that we got really fun jobs, but it's not who we are. Hopefully down the road that has more weight to it."

Dax agreed that the children will be faced with a "weird challenge" as they get older.

He said: "It'll all be what it'll be. They'll have this weird challenge of being privileged, which seems bizarre that that's a challenge, but that'll be their thing. We've all got a thing."
