Rob Kardashian has reportedly signed a deal to write a tell-all book about how fame has changed each member of his infamous family, reports Yahoo! News. The book will reportedly include juicy details about the relationship between his older sister Kim Kardashian-West and her husband, Kanye West.

"Rob was approached to do a tell-all book and he's recently signed a deal. He plans to claim that Kim sometimes uses her daughter North to promote Kanye West's tour and that her marriage is partly based on money and publicity," a source alleged to Closer magazine, according to femalefirst.co.uk.

The 28-year-old reality star has been struggling with depression since early 2014, and his relationships with certain family members have become strained. He reportedly flew to Florence for the May 2014 wedding of Kim and West but left without attending. Reports at the time suggested that he did not want to appear in front of cameras due to a recent weight gain.

The tell-all book deal could be Rob's way of dealing with deep-rooted anger toward particular family members. His rocky relationship with Kim has been well-documented. He made his feelings toward her publicly known on March 22 when he posted the photo of Rosamund Pike's "Gone Girl" character, Amy Dunne, on his Instagram account and wrote that Kim was "that b*tch."​ The post has since been deleted.

He had also unfriended his entire family on Instagram that day but later reconnected.

Rob is now supposedly livid that his mother, Kris Jenner, made his personal struggles the focus of Sunday night's episode of "Keeping Up with the Kardashians," in which Kris, Kourtney Kardashian, Khloe Kardashian and Kim discuss how to handle his downward spiral, reports Radar Online.

An insider told Radar, "Rob told Kris in no uncertain terms he is extremely upset that his personal problems are being aired on national television. This isn't going to help Rob in any way. If anything, it's only pushing him farther away from the family!"

Rob, who lives with sister Khloe, reportedly left her house without a word to anyone, which resulted in a minor crisis for the family just before Easter.

"Keeping Up with the Kardashians" airs Sundays at 9 p.m. ET on E!
