I'm A Celebrity... Get Me Out Of Here! viewers have spotted one of the campmates breaking a major jungle rule.

The popular series returned to screens over the weekend, with stars already taking part in rancid challenges. Marvin Humes, Josie Gibson, politician Nigel Farage, YouTube star Nella Rose and TV personality Sam Thompson are among the stars hoping to be crowned Queen or King of the Jungle.

According to viewers, JLS star Marvin has been sending secret heartwarming signals to his wife Rochelle Humes and their children at home, despite there being a no communications rule.

The singer was seen tapping his fist on his heart when he knew the ITV cameras would be on him as the names of those facing the Bushtucker trials were read out, which is always captured live meaning campmates know the moment will air.

Rochelle and their children Alaia-Mai, 10, and Valentina, six, and three-year-old son Blake have been supporting Marvin while he competes in the jungle.

Viewers rushed to social media to insist Marvin was sending signals to his family back home – however the moment appears to have gone unnoticed by the show's crew. "Is it just me or is Marvin thumping his heart a sign for Rochelle," one viewer tweeted as the singer repeatedly tapped his heart with his hand while everyone else was none the wiser.

Another added: "Awhhh seems like Marvin is tapping his heart to show Rochelle how much he loves her. He must miss his family so much already". One delighted fan commented: "Secret signal from Marvin 100%." Marvin, like the other campmates, made a scary entrance to the jungle on Sunday.

The star had to skydive from a helicopter, despite being terrified of heights. And while the show might have only just started, his wife and children already told him how proud they are of him, with the singer finding an emotional note hidden in his case on Wednesday after jetting off down under.

Speaking to the Mirror before entering the jungle, Marvin said: "When I left Rochelle and the kids wrote a note and stuck it in my suitcase which I found yesterday." He continued: "It said how much they loved me and told me how proud of me they are. My 10-year-old [Alaia-Mai] said, 'Daddy, I'm so proud of you conquering your fears, just don’t say no to anything and do your best.' That’s from my 10-year-old. You know, so, so sweet that she’s telling me to conquer my fears and get stuck in. I just want to make them proud."

He added: "My 10-year-old said to Rochelle that she doesn’t like going on roller coasters. And when we left she said: 'Daddy because you're doing this and conquering your fear, when you get out, I want to conquer my fear and I want to go on a roller coaster with you'." Thankfully, the star conquered his fear of heights and landed in the Australian jungle in style.
