After her showstopping press conference earlier, Beyonce Knowles appeared at a Super Bowl media junket yesterday where she teased fans about her upcoming halftime performance and snapped pics with fans. Check out her sexy tangerine look and see more rehearsal footage for Sunday's big event....

Beyonce (shown above with Miss America Mallory Hagen) touted her upcoming Super Bowl XLVII halftime performance during a press junket held at the Ernest N. Morial Convention Center.

Rocking the side swept big curls, she glammed it up in a tangerine Antonio Berardi Fall 2012 dress with gold mirrored leather Jimmy Choo pumps.

And Miss Tina looked pretty snazzy too in a red blazer, black slacks and black peep toe shoes.

During the junket, she chatted with NFL legend Deion Sanders and showed him a few moves.  She revealed that her halftime performance preparation has been very intense saying, 'I practice until my feet bleed..."

And during the earlier press conference, when asked about lip-syncing "The Star-Spangled Banner" during the Inauguration, she explained,

"I did not have time to rehearse with the orchestra.  Due to no proper sound check, I did not feel comfortable taking a risk.  'It was about the president and the inauguration, and I wanted to make him and my country proud, so I decided to sing along with my pre-recorded track, which is very common in the music industry. And I'm very proud of my performance.'

But yesterday, she assured the press (and millions of fans) that on Sunday, she will be singing live at the Super Bowl! 

And for another look at what you can expect on Sunday, here's more rehearsal footage:
