ITV’s Love Island is back on our screens with its All Stars spin-off, and the villa has already been rocked by two shock bombshells. Viewers were left completely floored as two exes entered the villa at the end of Monday night's launch instalment.The All Stars series, which debuted on ITV2 on 15 January, brought 12 islanders back from previous series, and then announced that the public had decided on their couples. But just as it appeared there were no more twists to come, former stars Callum Jones and Molly Smith were both brought back.The former couple, who dated for three years after starring on the show together, only recently split up a few months ago in September.They may have been the first bombshells, but they certainly won't be the last.
