A Green Bay Packers fan got back at her cheating ex-boyfriend in the best way possible - on national TV.

This very public revenge happened on Sunday night, when the Packers faced off against the Bears at Lambeau Field. The Packers might have won 35-21 but this female fan stole the show.

Her name is Annie Wagner, according to Deadspin's investigative reporting.  When NBC's cameras captured her cheering from the stands, the sign she held up became an instant hit.

Written in big red and green letters was MY CHEATING EX BOYFRIEND IS WATCHING FROM COUCH INSTEAD.

Needless to say, it probably was not the Christmas greeting her ex-boyfriend was expecting.
