PHILADELPHIA (CBS) – Taylor Swift is in the stadium at Super Bowl LVIII supporting her boyfriend, Kansas City Chiefs tight end Travis Kelce.

Since she started popping up in stadiums across the U.S. – not to perform, but to spectate – her influence has affected everything from viewership to sales.

The Super Bowl will mark Swift's thirteenth game of the season, and, by the way, 13 is her lucky number.

Back in September, Swift made her debut on football Sunday at Arrowhead Stadium.

CBS Sports reported that Travis Kelce jersey sales spiked nearly 400%, launching him into one of the top five selling jerseys in the NFL.

While their "Love Story" grew, Swift showed up to more games and sales kept jumping.

Small businesses like Wove, which made the tennis friendship bracelet seen on Swift's wrist after the AFC Championship game, saw more than 470% jump in sales.

In Atlantic City, Bar 32's "Love Story #87" Valentine's Day chocolate box led to its best February sales since the shop opened.

Front Office Sports first reported the pop star generated more than $330 million for the NFL and Chiefs, according to Apex Marketing Group.
