Love Island has shown us the cast who are set to burst into the villa on Monday night - but some are still convinced there could be a curveball on the way. Among the theories doing the rounds with just days to go until the ITV series returns is the theory that a newly-single Ekin-Su Cülcüloğlu is about to return as a bombshell.The rumours started when she posted a series of large numbers on her Instagram page with many trying to figure out whether they related to a stint in the villa.
