The singer-and-actress insists she keeps her skincare regime to a minimum and credits her appearance to lots of sleep, drinking water and relaxing.

She said: ' try to get enough good sleep, about seven or eight hours and I drink a lot of water.

' don't have facials or treatments. I don't like messing with my face or my skin too much. I don't do scrubs or peels or anything like that, I just do the basics. I use moisture masks a lot though.

'f I have a red-carpet event, I'll do a face mask in the morning. And I'll take a nice bath to relax myself because I think the better you feel, the better you look. Then I'll have a coffee and take the day slow. I don't like to rush.'

Jennifer ' who is married to Marc Anthony ' also admitted she struggled to get back in the exercise habit following the birth of her twins Max and Emme, now three.

She added to Company magazine: 'After I had the babies, I wasn't motivated at all. I did a triathlon, which was a goal I had set for myself before having them. I did it because I'd said I was going to do it and it was for charity. After that, I stopped exercising totally for a while.

' was tired, the babies were my life and I just wasn't motivated. It took a lot of mental energy to get focused again.'
