Basketball player Lamar Odom has reportedly demanded $10 million and a $875,000 engagement ring back from estranged television presenter wife Khloe Kardashian to end their marriage.
The couple has been staying apart for the past few months after Lamar was caught cheating on Khloe twice. He was later also involved in drug abuse.
Khloe's mother Kris Jenner is worried about Lamar's demands because she fears that he will disclose the secrets of the Kardashian family, reports dailymail.co.uk.
"Kris and Khloe are very worried about Lamar... He knows all about their extreme surgery procedures - when, how often and how much - and the pressure put on the younger girls to follow suit," said a source.
"Lamar is also prepared to destroy Khloe's reputation by discussing their sex tape and how she targeted him and tore his family apart," the source added.
Khloe and Lamar have been married for four years. Kris wants Lamar to sign a confidentiality agreement.
"Kris is insisting on a confidentiality agreement to ensure Lamar can never discuss his life with the Kardashians either in print or verbally," said a source.
