Is Martina McBride a traitor to the Tennessee Titans ... or is she helping her hometown team get revenge? The singer has performed the national anthem at the NFL team's home games more than 30 times, but couldn't help the team claim victory over the Baltimore Ravens in their recent playoff game at Nashville's LP Field. Now she's headed to Pittsburgh to perform the anthem as the Ravens face off against the Steelers for the AFC Championship at Heinz Field on Sunday.

McBride's home field record for the Titans when she performs the anthem is 26 wins and five losses, so we think she's hoping to strengthen the Steelers' home field advantage to get even with the Ravens.
