London: Actor Nicholas Hoult has signed up to celebrity dating app Raya. Hoult, who dated actress Jennifer Lawrence on and off for three years until 2014, is finding love online on Raya, which is preferred by discreet celebrities, reports pagesix.com. Apart from Lawrence, Hoult's name has also been linked to actresses Dianna Agron and Riley Keough. Other celebrities who are available on Raya include Joe Jonas, Kelly Osbourne, Moby and Olympic swimmer Ryan Lochte. Hoult was recently forced to deny he was dating his “Equals” co-star Kristen Stewart. “Of course there's always going to be speculation. But there's also like a whole business behind people kind of fuelling those fires and creating speculation. There's kind of a whole industry behind that at play that has nothing to do with the actual people,” he said at that time.
