Video: Rob Gronkowski Sings National Anthem at LA Bowl Ahead of UCLA vs. Boise State

Former NFL superstar tight end Rob Gronkowski helped sing the national anthem prior to the Starco Brands LA Bowl Hosted By Gronk between UCLA and Boise State on Saturday evening in Los Angeles' SoFi Stadium.

As the bowl's name suggests, Gronkowski is the bowl's host and de-facto emcee. He signed a multiyear agreement with the LA Bowl in October to partner with the matchup. Gronkowski took over for comedian and late night talk show host Jimmy Kimmel.

The 34-year-old Gronkowski is arguably the best tight end in NFL history. He's a four-time All-Pro, four-time Super Bowl champion and a member of the Pro Football Hall of Fame's All-2010s team.
