Karlie Kloss doesn't have time for a lengthy beauty routine since becoming a mom

Karlie Kloss has simplified her beauty and fitness routines since becoming a mom.

The 31-year-old model - who has sons Levi, two, and Elijah, 4 months, with husband Joshua Kushner - has had to minimise everything to fit it in with her hectic family life.

She told People: "It's not a 45-minute beauty routine anymore. I don't have time for that. It's like, what are the small things with two minutes, four minutes that I can do?"

Of her exercise regime, she said: "My philosophy has gotten to be much more about strength.

So I do light weights and body weight exercises. I do so many at-home workouts now."

Karlie no longer has a restrictive diet and instead focuses on fuelling her body with the right nutrients to give her energy.

She added: "It's this funny thing.

"It's like, until you experience it you don't understand how much it really does change your life, and it changed my own relationship with my body. I think now I do what I can to just rest, recover, and eat what's going to fuel my body.
