JLO the award show host? Jennifer Lopez is set to return as both host and performer for this year’s American Music Awards, airing live from Las Vegas on Memorial Day, May 26, on CBS and streaming on Paramount+ in the U.S. This marks Lopez’s second time hosting the ceremony, following her role in 2015 where she opened the show with a performance of her Grammy-nominated hit, “Waiting for Tonight.” Lopez has performed on the AMAs over 10 times, and has collected three awards over the years.
