Here's a case Elle Woods probably wants no part of. Reese Witherspoon's mother, Mary Elizabeth "Betty" Witherspoon, is suing the Oscar winner's father, John Witherspoon, for bigamy.
Wait, what? Let us explain.
While Betty and John have been separated since 1996, the "Legally Blonde" star's parents are still legally married.
As a result, Betty is seeking to have John's Jan. 14 marriage in Tennessee to Tricianne Taylor annulled, USA Today reports.
In her lawsuit, filed against both John and Tricianne, Betty insists she is still in love with her husband and does not want to divorce him.
What's more, Betty believes John is suffering from early-onset dementia and that Tricianne might be taking advantage of his condition, stating in court documents that Tricianne is already living in a Nashville condo owned by Reese as well as getting John to change his will.
"When I confronted my husband, he said he didn't know who Tricianne Taylor was and that he did not remember getting married," Betty said in the affidavit. "I also fear for my husband's personal safety and the safety of my family."
In addition to wanting John's marriage to Tricianne annulled, Betty has also asked the court that Tricianne be forced to return any vehicles, jewelry or other property acquired since she and John tied the knot.
Meanwhile, E! News has obtained a show cause order for an annulment and a restraining order filed on May 9 by Betty against John and Tricianne.
In the restraining order against Tricianne, Betty says that she is "hereby enjoined and restrained from using or attempting to use the last name Witherspoon." It also states that she is further enjoined and restrained from obtaining or attempting to obtain credit or taking personal property posing as the wife of John.
They are all due in court on May 31.
