(Cover) - EN Star Style - Jennifer Lopez says her children can always tell when shes preparing for a night out.

The 41-year-old Latino beauty is famed for her stunning good looks and gorgeous curves. The singer-and-actress has three-year-old twins Max and Emme with husband Marc Anthony, and is amazed by how perceptive they are.

Jennifer says as soon as she disappears to put on her make-up or do her hair, her children will quickly follow suit.

Theyre starting to be able to express certain things. Like when I start putting on hair and make-up and getting dressed, they know Mommy is going somewhere. So that can be difficult, she explained.

As much as Jennifer enjoys motherhood, the star says she rarely gets to have any time to herself, so her beauty regime gets ignored. The star is a massive fan of long soaks in the bath, although she is usually not alone in the tub anymore.

It can be hard. Sometimes its like literally Im taking a bath and Max is off with the clothes and in the tub with me or the shower. You dont have a minute by yourself. Go to the bathroom? Baby standing right there. Im like Go outside. Emmes like No way. So yeah, its tough, she told Hello! magazine. (C) Cover Media
