Jennifer Lopez reveals her secret weapon

Jennifer Lopez has revealed the secret to her stunning looks - beauty sleep.

The actress-turned-singer, who is married to Latin star Marc Anthony, makes sure she gets at least 8 hours slumber a night to ensure she stays looking great.

She revealed to Top of the Pops magazine: "Sleep is my weapon. I try to get eight hours a night. I think sleep, water and a good cleanser works best."

Despite being considered one of the most beautiful women in Hollywood, J.Lo insists she can't always look fantastic - no matter how hard she tries.

She added: "I'm only human. I can't always look my best."
