Idina Menzel always wants to put her son first.

The 'Frozen' star feels it is important for her and her ex-husband Taye Diggs to prioritise their seven-year-old son Walker despite their split.

She said: ''Your child comes first, that's all. It's all about that. He comes first and you have to get past your own egos and you never talk bad about each other.''

And with all the horrible things going on in the world, the 45-year-old actress and singer is conflicted whether she should explain to her son what is going on.

She added to People Now: ''It's hard to know what's age-appropriate as far as educating your child and how much to teach him about what's out there, and that there are bad people out there and there are people who don't like other people. You want to keep him insulated and safe and not ruin his perspective of the world.''

Meanwhile, Idina previously admitted her divorce has taught her not to be so hard on herself.

She said: ''You learn to try to not be so hard on yourself. You have a lot of regret with a child, feeling like you're failing them in some way and not giving them the idealistic scenario.''

Idina has recently got engaged to Aaron Lohr and is thrilled to have a ''new beginning''.

She added: ''I'm super happy, yeah! Very happy. I'm happy because it's all coming together, everything feels good. I went through a lot of stuff and its new beginnings.''
