The bitter divorce between Kim Kardashian and Kris Humphries could get nastier because the NBA star's legal team is considering issuing a subpoena for the reality star's ex-boyfriend, Reggie Bush, to be deposed, Breaking Celebrity News is exclusively reporting.

Team Humphries is now "gathering information from the men, including ex-boyfriend, Reggie Bush,” a source close to the situation tells Breaking Celebrity News.

As Breaking Celebrity News previously reported, Kardashian's legal team has formally subpoenaed Kris' ex-flame, Myla Sinanaj, to dish about her relationship with the NBA star.

Humphries accused the New York City hotel worker of attempting to extort him for millions of dollars because she allegedly threatened to go public with intimate details of their relationship. Myla's pit-bull attorney, Joe Tacopina, previously told us that there is absolutely no evidence that she ever asked Humphries for any money. 

Humphries' attorneys will issue a subpoena for Kim Kardashian's boyfriend, Kanye West, to be deposed. The gloves are now off because Kim is dragging Humphries ex-flame into the divorce, and for a very long time Kris' lawyers wanted to go after the men in Kim's life, but he didn't want to put her personal life under scrutiny--however, the New Jersey Nets b-baller has given the green light to his lawyers. “There were reports late last year that Kim was considering getting back together with Reggie, and his lawyers would like to know what she said to him about the divorce, and her decision to file for divorce,” the source said.
