Luke PerryLuke PerryWe like to think of our celebrity comrades as being a big group of mates.

And that they all hang out together when they're off set.

But clearly, that isn't always the case.

In fact all too often, they seem to work for months together on a project, then when filming is over, they go their separate ways... never to see each other again.

So it warmed our hearts when we spotted pics of Luke Perry hanging out with an old co-star of his.

And as fans of Beverly Hills 90210, we were even more delighted to think that two of our former heart throbs are still buddies, six years after the show ended.

The twosome had been for lunch together in LA village and were snapped as they waited for their cars to be delivered back to them.

See who we're talking about in the gallery above.
