Gwyneth Paltrow's "toughest job" is getting her son to do his homework.
The 'Mortdecai' actress - who has eight-year-old Moses with her former husband Chris Martin - has joked that she struggles to get her youngest kid to do his schoolwork.
She said: "Definitely getting Moses to do his homework, that's my toughest job for sure."
Not only does Gwyneth - who also has 10-year-old Apple with the Coldplay front man - have to work hard as an actress, she also runs her own successful lifestyle website Goop.
She admits, though, that she was a "fool" at the beginning but has since found it "incredibly rewarding" having created her own digital business.
She said: "I was a fool and I had no idea what I was getting myself into. But I have to say it's been incredibly rewarding.
"I learn so much every day and we're in a really exciting time in the business right now and it's amazing to be the creative force and also to understand what's going on the fiscal side and with raising money and all of that."
The 42-year-old actress also hopes one day her children will take over the reigns of the business and is slowly making her part in the website less "essential".
She told Bloomberg's Market Makers programme: "I very much want Goop to be its own standalone brand. I know at this point it's inextricably me but we are a team of amazing people who bring incredible ideas to the site and it's not only me and my dream would be that in 20 years people would sort of recollect that I had something to do with it at one point and my involvement would be less essential.
"I never wanted to do a proprietary brand. I wanted it to be its own thing that my children can run one day if they want to."
