Stephen Bear's fiancé Jessica Smith shared a picture of the letter he sent to her from prison.
The disgraced reality star, 33, was sentenced to 21 months in prison at the beginning of March after secretly recording a video of him and ex-girlfriend Georgia Harrison having sex.
Jurors heard how he filmed it on CCTV and then made at least £40,000 on the X-rated site, OnlyFans, by uploading the clip.
And now, Stephen's fiancé shared a snap of a partly-redacted letter he wrote to her.
Jessica captioned the post: "I get so excited checking the post box for letters... he is sooooo cute makes me melt every time seeing his handwriting."
She then referenced a rabbit he drew at the bottom of the letter.
"Look at the drawing... actually made me laugh out loud," Jessica commented.
Stephen's letter reads: "You're doing amazing at home. I'm so proud of you!
"It helps me having more credit and I can call you all the time. I love you with all my heart and I don't want you to worry about anything xxx."
He signed his name at the bottom of the letter and surrounded it with hearts and kisses.
In another Instagram Story, she answered a fan's question about how she's been feeling.
She said: "I don't think I'll ever be OK until I get Stephen back, but I've sort of adjusted to being on my own in a way.
"Me and Stephen lived together, we did everything together, so to have him taken from me I've had to learn to do everything on my own again.
'I'm doing OK. I'm doing better than what I was."
It comes after it was revealed that Stephen is reportedly spending all of his prison wages on tearful phone calls to his fiancé.
He is said to earn £5 a week in prison by packing tea and coffee.
Bear reportedly uses his earnings to make emotional calls to OnlyFans content creator Jessica, costing 16p a minute.
The Sun reported the money is paid into the shamed star's prison bank account and is his only source of income.
