The Minnesota Vikings careful plans for a new billion-dollar stadium have apparently just been intercepted by Wells Fargo. Now the team is trying to sack the financial firm with a lawsuit.

In a lawsuit filed this week, representatives for the Vikings argue that Wells Fargo is effectively "photo bombing" their precious new stadium, called the U.S. Bank Stadium because of its sponsor, with plans to place large illuminated signs on top of its two office towers nearby.

"Wells Fargo has recently started installing mounted and illuminated roof top signs that do not conform to the parties' agreement in an effort to permanently 'photo bomb' the image of the iconic U.S. Bank Stadium," the lawsuit reads.

Apparently it would be OK, based on their previous agreement, to have the giant 56-foot signs if they're not lit up. But illuminated signs? GTFO.

The team, according to the lawsuit, "has worked diligently to create and promote the development of an iconic, bold new stadium... These efforts included... negotiation of multiple agreements with its neighbors to control and protect the image of U.S. Bank Stadium, since it will be an important landmark in this State for years to come."

Translation: U.S. Bank paid a reported $220 million for naming rights to the flashy stadium and now it's about to be partly overshadowed by rival Wells Fargo, who paid nothing.

Talk about a branding fumble.
