What's Julia's Secret?

All hail Julia Roberts.

We feel we need to heap on piles of admiration.

The lady is 40 later this month.

Yes you heard right - Miz Roberts is hitting the big 4-0 on 28th October.

And the wonder of it is she doesn't look a day over 25.

Is she sipping from the cup of eternal youth?

Cos this surely is mightily unfair otherwise.

In fact we had a bit of a gander at Jules throughout her starry career and we couldn't believe what we saw.

Nothing, nada, zilch.

There's been barely a jot of change when it comes to her fair visage.

Frankly, it's only her hair colour and bushy brows that show the passing of time.

Her smile is as perfect now as it was back in 1991 when she starred in Pretty Woman.

Don't just take our word for it - we've put her together an early b'day pressie and bundled up a whole heap of pictures tracking Julia Roberts over the years, right from her girly beginnings.
