“We wake up really early in my house – 5:45 a.m. I’m a single mom trying to get two kids ready, pack the lunch boxes, and not miss the bus. When I wake up I just rinse my face and put on sunscreen,” Theron told Harper’s Bazaar.

The 43-year-old actress has a very strict exercise regime and has said she tells her children she works out so she can “make sure her heart works for a very, very long time”.

She said: “When I leave to go exercise, my kids will say, ‘Where are you going?’ I tell them that I’m going someplace to make sure my heart works for a very, very long time! I’m always calculating my activity.

“If I haven’t been moving a lot, I can’t eat a lot. Or maybe it’s a cheat day. But I’m honest with myself.”

Theron always puts on fragrance before the leaves the house and sees it as her “slice of luxury”.
