Katy Perry has hinted she's ready to move on from Russell Brand, telling a pre-Super Bowl crowd that she feels "brand new".

The songstress has rarely appeared in public since Russell announced their impending divorce at the end of December. However, the star looked in good spirits as she performed on DirectTV's Super Saturday Night, ahead of Sunday's Super Bowl XLVI.

Katy addressed the crowds at the event and hinted about her positive frame of mind following her highly-publicised relationship breakdown.

"We just finished 125 tour dates. So everything feels brand new," she told the audience, before beginning her song The One That Got Away.

Katy also seemingly acknowledged rumours she is romantically involved with Denver Broncos quarterback Tim Tebow.

The stunning star dedicated her song Peacock to the NFL sports star.

"This goes out to Tim Tebow," she said.

Following her performance, Katy enjoyed her night in a VIP area at Victory Field in Indianapolis. Onlookers told the New York Post that the star "appeared to be having a really good time. She was smiling and laughing".

Reports recently emerged that Katy's estranged husband has been in contact with Katy lookalike Zooey Deschanel.

The British comedian is said to admire Zooey's talent, and has been sending text messages over the past few weeks in a bid to meet up.

"Russell is a big fan of Zooey and would love to work with her in the future. He's been in contact, asking to meet up," a source told Closer magazine.

"He thinks she's hysterically funny and cute too. He loves her quirky sense of humour. There seems to be a spark there."
