Taylor Swift is joining the max exodus in Las Vegas ... flying out of the desert after her boyfriend Travis Kelce's big Super Bowl win.
The singer hopped on her private jet Monday for a short flight to Los Angeles ... and she was joined by good friend Blake Lively. We're hearing there might've been other stars in the mix as well -- but hard to make anyone out specifically ... including TayTay.
Taylor's team was definitely trying to shiled her from the cameras behind a wall of black umbrellas as she climbed the stairs onto the plane .
