Lance Bass is not the Swifties' lord and savior -- something he made abundantly clear at Monday night's Chargers game ... in hilarious fashion, no less.
The *NSYNC star was among a handful of stars at SoFi stadium during MNF -- and as the broadcast was going and cutting to different people in the crowd ... they eventually landed on LB, who was sitting in a private suite with his crew.
It looks like he was ready for the close-up ... because he had a sign propped up when they eventually panned to him, and it read "NOT TAYLOR SWIFT." He was smiling and waving -- and everyone seemed to get a kick out of it ... including fellow patrons.
It's just the latest joke someone has cracked at the expense of the NFL ... and Taylor, too, if we're being honest. There's been wall-to-wall coverage of her relationship with Travis Kelce -- which has reached a fever pitch whenever she's shown up to one of his games in person.
