Pop star Katy Perry has sparked rumours of dating British rocker Winston Marshall after they were spotted hooking up in Berlin over the weekend. With the new hook up, the 30-year-old “Roar” hitmaker has also sparked speculation she has split from John Mayer once again, reported the New York Daily News. Folk group Mumford and Son, which Marshall is a part of, met with Perry following their intimate show at the Magnet Club in the German capital “They danced the night away at the trendy nightclub Schwuz,” an onlooker said. This would not be the first time a member of the popular band has found love with an A-list celebrity as the lead singer Marcus Mumford is married to Hollywood actress Carey Mulligan, 29. Perry and Mayer, 36 – who have had an on-off relationship since 2012. (PTI)
