Travis Kelce did NOT host a big shindig in Sin City a couple nights before the Super Bowl, despite his name being on the invitation for a house party ... TMZ has learned.
There was an invite going around social media Thursday promoting "The Kelce House Party" later that night in Las Vegas ... with Travis' name prominently displayed above the RSVP. Of course, many quickly wondered ... is TK partying his off just a few nights before the game???
Understandable -- on its face, the invite made it seem like Travis was hosting the party with his brother, Jason, which was billed as an event for their 'New Heights' podcast .
