For the latest shopping task, the housemates have been able to get in touch with their friends and family, either through video messages or actual visits into the house, and Renee had revealed her upset at not having heard from any of her loved ones.
Instead, she was distracted by a stripper during her concentration task, while Sam Fox saw her mum and Bear was confronted by ex-girlfriend Lillie Lexie Gregg. However, Renee has now heard from a familiar face, after being treated to a letter from her son.
In a new video shared by Big Brother, Renee comes over all emotional as Lewis reads out her son AJ's letter to her.
He says: "Mum, wow you're hanging in there. I'm so proud of you. I thought you would have lost it by now, maybe you did a little from what I've read. Lol. I didn't realise I would miss you this much. It's been a long time and it feels weird being out here alone in a way. But, of course, Aunt Jenny is there... I've been at work everyday doing double so you would be proud of me.
"I went to grandma's and grandpa's on Sunday and they were asking about you too. I'm with Andrea right now and she can't believe how much she misses you either. Keep up the good work and don't let that... Bear get in your head."
It's no secret that Bear and Renee haven't exactly seen eye-to-eye, despite forming a close bond at the start of the series. They did, however, call a truce and predicted there'll be "no more arguing" now in the house.
Lewis continued: "Aunt Jen says you better win and to just tune [Bear] out, like she does to you... You're doing great and I love you. I can't wait to hear about London when you're back. Next time, I'm definitely coming. Love and miss you, AJ."
Renee was comforted by Aubrey and Frankie as she took in what AJ had to say, receiving a round of applause from her fellow housemates.
Meanwhile, Lewis receives a surprise visit from his mum. He gushes about girlfriend Marnie Simpson to her and says: "[Me and Marnie] have so much fun and giggle and laugh all day. I feel really sorry for everyone else. We must be irritating them."
Oh, and he also drops a bombshell that he thinks Marnie could be The One!
