Among those cheering loudest from the stands of the Superdome was Stacy Keibler.
Baltimore Ravens most famous former cheerleader was in town to support her team as they took on the San Fransisco 49ers. She slipped on the team's purple jersey and posed with a friend outside the venue's gates before heading inside.
Also attending the big game, which took place in New Orleans, was Vampire Diaries beauty Nina Dobrev. Joined by her brother, she could barely contain her excitement as she shared pics with her fans ahead of the game.

The 49ers had a famous fan in pop singer Katherine McPhee, who was spotted showing her colours with the team's name painted on her cheek.
Elsewhere, stars tuned in from the comfort of their own home.
