Leave it to Katy Perry to use Sunday's Super Bowl as an excuse to rock an over-the-top football-inspired outfit.

The newly-single singer, 27, got dressed up for the pregame show in New York Giants and New England Patriots gear that read "Perry" on the back at Lucas Oil Stadium in Indianapolis, Indiana.

She accessorized with red sunglasses and mismatched red and white Marc by Marc Jacobs high top wedges.

"There's a big game @ the Madonna concert tonight! #XLVIPICS," she joked on Twitter of the buzzed-about half-time show. 

On Saturday, Perry posed for pics in a multi-colored Versus pleated dress with a purple fur vest and Christian Louboutin sandals at DirecTV's pre-Super Bowl XLVI party before performing her song, "Peacock."
