Tim Duncan's wife, Amy, reportedly outed him as being bisexual during their divorce proceedings.  While married, the Spurs forward allegedly had a gay affair with a close friend from his college days.

Amy supposedly said Tim was involved in a longtime homosexual relationship, according to the Hollywood Street King (via Newsone).  An anonymous source told the gossip blog that Tim was involved with an unidentified man from his playing days at Wake Forest University.  The man later reportedly lived with Tim and Amy for the first two years of their marriage, before Tim purchased the man a home.

HSK added that Tim is seeking to place a gag order on his wife.  The blog's source also insinuated that Tim tried to placate his wife in every way to keep his affair a secret.

"Amy treated Tim like a b---- throughout their marriage because she knew he was f---ing his BFF," the source told HSK, via Newsone.  "Tim knows Amy was cheating on him but he's willing to give her whatever she wants, because he doesn't want Amy to tell the world that he's bisexual."

Amy filed for divorce on March 27, citing the marriage as insupportable due to conflict and discord.  Duncan allegedly had her followed and confirmed that she was having an extramarital affair with her trainer, according to LatinTimes.  Based on HSK's report, her affair appears to be in response to Tim's own affair.

The veracity of HSK's report is uncertain.  Neither Tim nor Amy has addressed the rumors, and, as of Friday, HSK appears to have removed its original article.

Tim, 37, and Amy have been married for 12 years and have two children together.
