Bruce Jenner and Kris Jenner have announced their separation, but the Olympian's sons are happy they are splitting up.

According to TMZ, sons Brody and Brandon Jenner blame Kris for their estranged relationship with their father.

"They were raised by their mom, Linda Thompson and David Foster, who married Linda after she divorced Bruce," TMZ reports.  "We're told the boys were devastated, and believed their real dad abandoned them.  What's more ... our sources say Brody and Brandon believe Kris is the one who convinced Bruce to jettison them, in favor of his new family.  They have bitter feelings toward Kris, which endure even today."

The boys are now rebuilding their relationship with their father on an "adult level," even if that meant appearing on "Keeping Up With The Kardashians" while he was filming, according to TMZ.

Kris and Bruce are not the only ones who are facing marital problems.  Kris' daughter Khloe Kardashian may try to seek a divorce from her husband Lamar Odom due to an alleged drug addiction.  The couple reunited on Oct. 8 to reportedly talk about their issues.

"Their talk was filled with a lot if emotion, mainly Khloe telling him how she can't do it anymore," a source told HollywoodLife.com. "She poured out her feelings and told him that she'll never stop loving him and that he's her heart and that his actions are making it bleed to the point where she can't breathe...She told him she doesn't want him to sh*t on his life and die and that it would kill her to bury him."

The stress of Khloe's situation with Lamar is reportedly taking a physical toll on her.

"She told him she can't sleep and doesn't eat because she's worried about him day and night," the source added. "She basically told him the stress is getting to her, and her family is concerned that she might have to go to the hospital for severe anxiety. She was crying to him, and she took him into the house and he got more of his sh*t."
