Katy Perry partied until 3am with the New York Giants after they won the Super Bowl.

Katy performed on DirectTV's Super Saturday Night, ahead of Super Bowl XLVI on Sunday. She was in great spirits and hinted she was ready for a fresh start following the end of her marriage to Russell Brand after telling the crowd "everything feels brand new".

Katy stayed on in Indianapolis to watch the New York Giants triumph over New England Patriots on Sunday. She then helped the American football stars celebrate their win at the team's hotel.

"The Giants celebrated their Super Bowl victory Sunday with Katy Perry. The team partied with the pop star until 3am in a second-floor function room at the team's hotel, the Marriott, in downtown Indianapolis," reports New York Post. "Spies said Perry was spotted going up to team co-owner Steve Tisch and congratulating him, and also chatting with tight ends Travis Beckum and Jake Ballard."

Katy is clearly developing an interest in American football.

She has been romantically linked to Denver Broncos quarterback Tim Tebow. During her energetic performance on Saturday she dedicated her sexy song Peacock to the NFL star.
