RESSE WITHERSPOON’s father accused of bigamy charges by her mother, according to legal docs!

While Reese, 36 is ready to be a mom with hubby/agent Jim Toth, her mother Betty Witherspoon has sued husband John Witherspoon in Tennessee — accusing him of bigamy.

Betty Witherspoon claims John can't be married to Tricianne Taylor, whose wedding to John was announced in the local Tennessee media last month because John is still legally married to her.

The wedding announcement published April 22 stated John Witherspoon and Taylor were married Jan. 14, with a summer reception to be held in Nashville.

In the bombshell lawsuit, filed against John Witherspoon, 70, and Taylor, 60, Betty Witherspoon says she is still very much in love with her husband, and does not want a divorce.

In the lawsuit, Reese’s mom Betty describes her husband as having troubles — with drinking, hoarding and money issues.

In the legal docs, she claims that she thinks Reese’s dad is beginning to suffer from dementia.

"When I confronted my husband, he said he didn't know who Tricianne Taylor was and that he did not remember getting married," she said in the affidavit.

In the court filing, Betty says that Taylor is living in a Nashville condo owned by their famous daughter Reese Witherspoon, and that the new “bride” has had John change his will.

"I also fear for my husband's personal safety and the safety of my family," Betty Witherspoon said in the filing.
