Rochelle Humes' sister Sophie Piper is set to be heading into the Love Island villa on Sunday.

The 21-year-old was recently announced to be among the first contestants for winter Love Island.  And Rochelle took to Instagram to send her sibling a good luck message before the series kicks off - and urged her to "bring us back a keeper." "Good luck baby sis," the mum-of-two wrote underneath Sophie's post confirming she would be on the show. "Bring us back a keeper." And Rochelle's husband, Marvin Humes, also shared a message of support in the comments. "s this how far @rochellehumes will go to make me watch Love Island?!" he jokingly wrote. "Good luck Soph x" The first season of winter Love Island is due to kick off on January 12. Much like its summer counterpart, the series will see twelve singletons enter a luxurious villa in the hopes of finding love - you can find the initial lineup of Islanders here. Laura Whitmore will be hosting the new series after Caroline Flack announced last month that she would be "stepping aside" following her assault charge. And the Bray presenter has said Flack has been "incredibly gracious and supportive" of her taking on the hosting duties for winter Love Island.  "She’s a brilliant host and I just hope that I can give the role the justice it deserves while she is taking some time off," she told The Mail Online. Laura said that when she got the call to host the series, she was straight on to her boyfriend, Iain Stirling, to make sure he was comfortable with her taking on the job. "When I initially got the call, I had a conversation with Iain. It’s his show," she said. "I said, ‘How would you feel about it?’ We both agreed straight away."
