Charlotte Crosby "stalks" Vicky Pattison online.
The "Just the Tattoo Of Us" star admitted she can't help but make regular checks on her former "Geordie Shore" co-star - who she reportedly fell out with in 2013 - but is usually relieved to see her rival is pretty "boring" on social media.
She said: "I want to see what she's up to and what she's been doing. Her Instagram can get a bit boring though."
Charlotte, 27, is smitten with her "Just the Tattoo Of Us" co-host Stephen Bear - who previously dated Vicky - but admitted she is constantly terrified he'll do something to hurt her.
In an extract of her book "Brand New Me" published in Closer magazine, she writes: "He scares me because I know he has another side to him.
"I've never been scared by a boy like I am with him, but he keeps saying he would never hurt me."
The reality TV star also admitted she had counselling after suffering from body dysmorphia and constantly feeling "fat and s**t" about her appearance.
Charlotte - who has had Botox and lip fillers, as well as a nose job - said: "I keep breaking down. I just feel like I'm not good enough. I'm getting anxiety. I feel so down and awful in myself.
"I have got to the point where I hate looking at myself and think I'm fat...
"When I look at old pictures of myself now, I can't stand it. I think I look so ugly. My old face was so fat it looked like I was swallowing my facial features."
