7. Bruno Mars and Rita Ora
Rita's string of romances have been highly publicised but we bet you didn't know that she dated Bruno Mars! Before the two became chart-topping popstars, they began dating in 2009. Speaking on their relationship she said: "It was love at first sight, such a great experience...Our time together was wonderful," Rita said. "But once we got famous, work got in the way. We ended it last year. But we remained close."
