Emmy Rossum -- Real Knicks Fans ... DON'T ROOT FOR THE NETS!
Description:Emmy Rossum is a die hard Knicks fan ... DIE HARD ... and she doesn't take kindly to people who jumped ship to root for the Nets because Jay Z told them to. Rossum was at LAX this weekend -- proudly rockin' her Knicks hat -- when she admitted it's been hard being a NY Knicks fan over the years, but says ... "I love my team so I don't give up on them." Then she fired the shot -- "I didn't just hop to the Nets 'cause they were cool ... like other people."(0:37)
