I believe I stated this in an earlier thread but Reggie Bush was sporting a Steeler jersey and a Pirate hat during an interview on ESPN a few months back.
That Chris dude from that boy band? Forget his name and frankly don't really care to know it. He's from here unfortunately and sang the National Anthem earlier this season.
As for Snoop. He actually likes the Raiders and Steelers. Take that for what it's worth.
