The ex-Corrie star was surprised by the letter during the BBTV task and was given it on an autocue to read out as part of the shopping challenge, which features her playing a newsreader.
After watching Julie reading out the letter, Coleen Nolan commented: "That's a little bit of reality that makes you think it doesn't matter.
"It matters so much in here, but in the grand scheme of things in life, it doesn't matter.
"When you know that someone at home loves you, that's all that matters."
Prince Lorenzo commented: "That was quite nice, it shows they do have a pulse."
He told Julie later: "I learned from this show how much I miss my life, my friends, my family and my job. Everything I take for granted every day."
Julie Goodyear, Martin Kemp and Prince Lorenzo face possible eviction in tomorrow night's midweek live show.
