// “Pants On The Ground” Live in Vegas!//

“General” Larry Platt is finally cashing in on his “Pants on the Ground” phenomenon — because “American Idol’s” favorite senior citizen is now getting paid to play in Las Vegas.

Platt is scheduled to perform his semi-hit at JET nightclub at the Mirage Hotel on Friday.

Sources at the hotel say Platt is being flown from Atlanta first class … and will get pampered with free food, lodging, several thousand dollars and, last but not least, a steak dinner!

TMZ spoke to Platt’s manager, who said this is just one of many shows Mr. Pants has booked recently … which means the old man is finally getting the money his musical genius deserves.
