I was at a hotel bar in my city after a celebrity/charity golf outing. Yes, many drinks were involved. Yes, many hot woman were there. A local celebrity that most from my city would recognize was all over a decent looking blonde. Now my question is, I have met him and his wife a few times, and this was not his wife )no, they are not divorced or separated or split up, I asked around, discreetly). I did know her to be a provider from the area - yes, I have seen her website too. My question I guess is, I do know the family through a very good friend of mine - do I bring it up to him, do you leave it alone, or go Tiger Woods on him straight to the media?

What business is it of yours?  NONE
Would you want someone to go to your wife/SO and tell you that you hobby?  

Just leave it alone period....celebrity or not.
We are supposed to be supportive of each other so why would you want to mess that up?

Unless the national inquirer offers you like $50.00

The world hates a snitch. Karma has a way of snapping you back in the ass. Leave it alone.

If he is that indiscreet(not a put down but observation given the info in the OP) that he was publicly "all over the blond" I'll bet the wife may have an inkling about what goes on and she herself was her spa getting a massage with happy ending from a very hot masseuse...(one can only hope).

They may have an arrangement. Leave it alone. And why would you do something so... Oh I don't know, stupid as to go to the media? For what purpose except to hurt the family or for your own malicious adventure?

and move on.

Why would you even think about "doing" anything? What possible reason would you have? Just smile, and say "good for him".

Assuming that you know him well enough to approach him, I don't think it would be out of line to give him the heads up that you'd seen him, and that others could have the same opportunity.  Sort of a "I'm not gonna tell your wife, but I can't speak for the next guy, so watch your back" message.  Then again, if he's the guy on the 11pm news that doesn't know you from shit, leave him alone and let the chips fall where they may.

You don't many friends, do you?

Can't figure out which part of the anatomy some use for thinking!

do I really hear someone who is blabbing on a P4P discussion board talking about outing another person for being with a provider in public!? Am I really hearing this? What if they were civvie friends? What if they just met and he didn't know?

Too many moving parts and you don't seem to know what you're doing.

Leave well enough alone.

don't know the circumstances. Best to leave it be.

I'd leave it alone because I agree if he's that out there with it he'll get himself in trouble soon enough
