Sinanaj who is reportedly expecting Humphries child, has also asked Kardashian to keep her out of their divorce drama, reports femalefirst.co.uk.
She took to Twitter to vent out her anger.
"Hey Kimkardashian why don't u enjoy ur Miami trip & stop sending private investigators to my house-Stop dragging me into your drama ," she wrote.
Sinanaj has been ordered to sit for a deposition trial at the end of the month as part of Kardashian and Humphries' divorce proceedings.
Last month, Humphries' attorneys were said to be planning to issue a subpoena to Kim's boyfriend-singer Kanye West.
