Another long-term wedding is coming to an end -- Joe and Tina Simpson are divorcing after 34 years of marriage.

According to the documents obtained by TMZ, Jessica and Ashlee's mom is the one who filed for divorce in the family's home state of Texas in Sept., saying, "The marriage has become insupportable because of discord or conflict of personalities."

The family also issued the following statement:

"It is an amicable split and there is no third party involved.  Any other related allegations are completely false. The family appreciates your respect for their privacy at this time."

Rumors of trouble in the marriage have swirled for several months, especially after the couple recently listed their huge Encino home on the market for $4.395 mill.
