The singer’s appearance was teased at the end of Friday’s show and shortly after the episode, Craig posted a short video on Instagram.
In it, he explains his plan to bring “good vibes” to the villa, reminding viewers: “These are real people in there. It’s real to people.”
“So just be mindful as always,” he said. “Be mindful that these are human beings. They can be fragile.”
Craig added: “I’m here in Majorca and I’m very excited.
“The islanders don’t get to hear any music when they’re in there. To be able to go in there and play music, it’s going to be really like healing. Imagine not having any music.
“Hopefully I can bring some good energy, some good vibes.”
Friday’s episode saw Amber Gill and Michael Griffiths begin to put their differences aside by speaking honestly about their relationship.
Their laughter left Joanna Chimonides worried that Michael could still have feelings for his old flame, who then took pal Ovie Soko to accompany her on a date.
Ovie has become resigned to losing Anna Vakili to Jordan Hames, while the (painful) break-up of Curtis Pritchard and Amy Hart looks to be complete.
Love Island continues on Sunday at 9pm.
