Brand, who was married to Perry from 2010 to 2012, tweeted out his support for the pop star, writing: "Super Bowl may be baffling to Brits but half time show will be amazing. Good luck KP."

Meanwhile, DJ and music producer Diplo, who reportedly had a fling with Perry this past April, couldn't get enough of the "ROAR" singer's performance. "Who's with me? Team Katy Perry #sp49," he tweeted moments before she showed up on the field on a giant mechanical tiger. "Ghost ride the tiger @katyperry."
Diplo also seemed to enjoy Missy Elliott's contribution to the halftime show, tweeting: "Currently getting my freak on."

He added: "I won 200 dollars betting on Katy's hair color."
While Brand and Diplo were tweeting about the 30-year-old entertainer, her former beau John Mayer was hanging out with Perry in person on Super Bowl Sunday. Her fellow halftime performer Missy Elliott shared a pic of the on-again, off-again couple at an after party, where they looked quite comfortable cozying up to one another.
Perry wasn't the only Super Bowl act that got some love from her ex. Taye Diggs doted on his ex-wife and mother to his son, Idina Menzel, during her performance of the National Anthem. He tweeted: "Yup. Baby mama crushed it at the Super Bowl."
