In one of the hottest, rum-soaked parties of Super Bowl weekend, Rolling Stone celebrated Bacardi's 150th Anniversary with a concert headlined by LMFAO, Lupe Fiasco, Cobra Starship and Gym Class Heroes. "Pregaming" celebs included Alyssa Milano, Akiva Schaffer, Anna Faris, Chace Crawford, Jessica Stroup, Joe Manganiello, Jon Hamm, Lance Bass, Matthew Morrison, Nikki Reed, Paul McDonald, Pete Wentz, and more.

The concert, dubbed "BACARDI Bash: 150 Years Rocking the Party," was the capstone in a series of parties held worldwide by the rum brand, which began in 1862 as a modest Cuban distillery. Puerto Rico Governor Luis G. Fortuno even declared February 4 "Bacardi Day" in celebration of the anniversary.
