Jessica Alba has got a brand new bob!

The actress, 28, sported a shaggy new haircut on Friday night while out at a Super Bowl party in Miami.

"My theory is that if you look confident, you can pull off anything," she has said. "Even if you have no clue what you're doing."

Alba, who walked the red carpet Friday alongside hubby Cash Warren, may not have been happy with the shorter look -- which has also been seen on Victoria Beckham and Katie Holmes -- and side-swept bangs.

The following night, she was photographed with a noticeably different 'do -- her hair was slicked back and pinned up at a party hosted by the Creative Artists Agency.
