Jennifer Lopez admits being a working mother can be "overwhelming".
The singer-and-actress - who has three-year-old twins, Max and Emme, with estranged husband Marc Anthony - says it's quite tough juggling everything in her life, but wouldn't want it any other way.
She told E! Online: "I just have this attitude towards life - you just gotta attack it. You just gotta go for it.
"Sometimes it can be overwhelming. I have a lot going on with the kids and everything, but you know, anytime I get tired or feel overwhelmed, I go, 'This is good. I'm alive. It's OK. I'm lucky.' I get tired sometimes, but to be quite honest, I love what I do.
"Anytime I get any feeling that feels like this is scary, this is too much, I'm like, 'Don't be so weak.' "
Jennifer, 42, loves being a mother more than anything in the world and recently said she envied the life of her children because they've already done so much.
She said: "They see everything, they go and do so much more then I have ever done in my whole life, in all my travels, and they're only three."
