Tiger Woods -- Why I'm a Nickelback Groupie ...
Tiger Woods just had a press conference moments ago, where he DEFENDED himself for attending a Nickelback concert last week -- unfortunately, he didn't explain how he was able to sit through it.
Tiger just took the mic in North Carolina, where he's preparing for this weekend's Quail Hollow Championship.
... and now we have that damn "Photograph" song stuck in our heads.
