Jennifer Lopez feels "timeless".

She said: "I feel youthful and in a sense almost timeless. In fact, I don't even think of myself in terms of age. I think of the way I feel - and that is very healthy and agile and fit."

Jennifer - who has four-year-old twins Max and Emme with ex-husband Marc Anthony - thinks she has become a better performer as she has gotten older.

She added to Hello! magazine: "I just toured the world and was singing and dancing in a very energetic show every single night.

"I didn't feel like I was any less able to do it now than when I was 28 or 25. If anything, I think I'm better at it now."
