Jennifer Aniston and Courteney CoxJennifer Aniston and Courteney CoxLife has imitated art where Jennifer Aniston and Courteney Cox are concerned.

They used to be Friends, now they're the best of buds.

And they're now so close, they're bordering on sisters.

Just look at this snap of them together at the premiere for The Tripper - could they hug themselves any closer?

Jen was out with Courteney and her hubby David Arquette to support their new flick, which not only stars the couple, but is also directed by David.

But don't fret for Dave - Jen also chucked a cuddle his way too. Sweet.

We chart the Cox/ Aniston partnership in the gallery above - and say hooray for celebs who get along.
