Is this true????

I've seen this twice and while I would love for it to be true...I question it.  I cannot find the original source...I'm wondering why he would go to Vegas at this time...it feels like the Prophet would say this at Conference...and on and on my doubts go.  I've googled it thoroughly...well, my thorough, so maybe someone else knows a trick to finding it.  there is no mention of it on his FB page. 

and...IF not true why would it be published and who published it? 

Very curious.
