The night drew a number of huge stars to the MGM Grand Arena, including Mark Wahlberg, Will Ferrell and Diddy, who tweeted throughout the night from his seat at ringside. “I got Cotto in a upset,” he wrote before the fighters touched gloves. As the night went on, Diddy changed his tune. “This is ugly live! A lot of blood,” he wrote. “Somebody’s gonna have a headache!” A few minutes later, he tweeted, “They need to stop this fight before he gets hurt,” likely referencing Cotto.
