Ellen gaming machines are not exclusive to MGM corp. Several other celebrities have gaming machines too. Also there are tv shows that have thier own gaming machines. Celebrities perform in Las Vegas. Ellen performing at any venue in Vegas is not suspicious to me.
-I recall something being mentioned about Ellen choosing to have her name licensed to a Gaming Company. And that its a bit more involved versus the casinos putting celeb names on the machines in their typical general manner. Dont know the source, post or if its accurate. If anyone has a recollection please post it. TIA
