Drew BarrymoreDrew BarrymoreIn the ever-fickle world of Hollywood...

This sure is a rare old sight.

Check out Drew Barrymore and her look of pure, unadulterated, genuinely happy loved-upness.

It's sickening, we know, but in the fast lane life of celebrity we have to highlight such unusual occurrences as and when they happen.

Plus this is Drew we're talking about - the lady whose taste in men is erratic to say the least.

There was a time when she was linked to all kinds of different chappers (and even a chapette once, as well).

But for some time now, Drew's had eyes for only one fella, in the form of actor Justin Long.

Drew and Justin are said to have hooked up on the set of He's Just Not That Into You around September last year.

And since then it seems there's no stopping the twosome - adorable or nauseating, depending on which way you call it - they're defo in lurve.

Justin has even spoken out about his blossoming relationship with Drew in the past, saying: "I've been very fortunate. I just feel very blessed and very happy."
