Turns Two U.S. Marines
into Vegas ROCKSTARS
So there he was, partying in Vegas ... when Marc Anthony noticed two U.S. marines hanging out at the Venetian ... and decided he was going to show his appreciation, by treating them to most kick-ass night EVER.
TMZ has confirmed ... Anthony approached the two marines and personally invited them to hang with him at Tao nightclub Thursday night -- hours before Veteran's Day.
We're told Anthony treated the guys like rock stars -- ordering bottles of expensive booze at a private V.I.P. table and making sure everyone knew they were the guests of honor that night.
Sources close to Marc tell us the singer was more than happy to treat the marines as a thank you for their service to our country.
