It’s not just about the Seattle Seahawks and the New England Patriots. For some, it’s all about the NFL's 2015 Super Bowl halftime performer, Katy Perry.

After betting on distinct details regarding Perry’s halftime performance at the Super Bowl, all was finally revealed during the game Sunday night. While most prop bets leaned toward Perry, 30, wearing her hair down and sporting a silver/grey dress during her appearance, the hitmaker did not deliver on those fronts. She did, however, perform the single most spectators believed she would, her 2013 hit, “Roar.”

While Paddy Power’s odds were 3-1 Perry’s first stage outfit would be silver/grey, the songstress showed up wearing a gold dress, complete with orange and yellow flames. Odds on that were 8-1. Among SportInteraction.com gamblers, odds were 20-41 Perry would wear a dress/skirt/coat/cape during her opening act. They were right!

Perry is known for changing up her looks and her hair is no exception. Despite her love for wearing her brown/purple/pink locks down, the singer opted to sport an updo during the game. Paddy Power’s odds stated that 4-7 she would wear her hair down while 5-4 believed she would wear her hair up.

During her 10-minute set, Perry performed a wide medley of songs, including her 2008 breakout hit “I Kissed A Girl” and “Firework,” but it was her first song, “Roar,” that kicked off the show. Fortunately for some bettors on Paddy Power, the odds were strongly in favor of “Roar” being Perry’s first song with 8-11 odds.
