He couldn't be happier about the change!
On Thursday at the Bravo upfronts in NYC, the Watch What Happens Live host told E! News' Alicia Quarles the upcoming 2014 shift was "a brilliant move."
"I think there's nothing Jimmy Fallon can't do," Cohen said. "He's got a great respect for what's passed, but he's totally fresh and new."
"He sings, he dances, he does comedy [and] he does skits," he added. "He's hilarious. And everybody wants to be his best friend…I couldn't be happier for him."
