When it comes to age-defying beauty it's generally agreed that Jennifer Aniston has pretty much got it covered.

The actress - who turned 40 last week - is looking hotter than ever these days - so what's her secret?

Well, according to Now magazine, the Marley & Me star supplements her diet and exercise regime and regular salon treatments with a few beauty tricks of her own.

A source close to the actress tells the mag, "What’s really cool is that the beauty changes Jen takes the most seriously are things that don’t really cost money and anyone can try."

Jennifer reportedly keeps her body in tip-top condition with a supplement called Pomegranate Power, which claims to target cellulite from within by boosting metabolism and detoxifying the body.

The report claims she also has a daily morning ritual to make sure she looks her best throughout the day.

To achieve her luscious pout, Jennifer "puts half a teaspoon of sugar and a little water on a toothbrush and scrubs her lips with it for about a minute."

Her wake-up routine also involves refreezable ice packs: "She lays the packs on her eyes for 10 minutes to avoid that 'worn-out' look."

As for that famous barnet, Jennifer "brushes her hair three times a day using a boar-hair brush."

Whatever she's doing, it's definately working as the pictures below show!
