Jessica Alba bribes her children with make up.
The 'Sin City' star has revealed she can get her daughters - Honor, seven, and Haven, four - to behave by offering them her favourite lipsticks.
She told PEOPLE magazine: "My girls are in my makeup all day long. They love putting it on me.
"Whenever they're fighting, I'm like, 'Stop yelling at each other and I'll let you put my lipstick on!'"
Meanwhile, the 34-year-old actress previously admitted she felt "judged" when she first became a mother.
She said: "Doesn't it feel like the mean girl thing from high school sort of just transforms into adulthood through motherhood? I think it has to do with hormones, right? ...
"And then your hormones go crazy again when you're pregnant and having a baby - and even when you're breastfeeding. And I feel like maybe it's just all those hormones, and people don't know where to put their energy, so they just start clashing."
And because of her own experiences, Jessica is careful about offering advice to other moms.
She added: "Now I'm one of those moms that gives you too much advice that you may or may not want. I think the biggest thing is that what works for you, or what works for your friend, isn't going to work for everyone. There is no right or wrong."
