It’s official: Speidi is really coming to an end.
Spencer Pratt’s divorce papers in his split with Heidi Montag were filed in the Santa Monica, Calif., courthouse Thursday afternoon, Jodeane Farrell, a lawyer for Montag tells PEOPLE.
“Spencer has acknowledged that the divorce is going forward,” Farrell added. “He signed the papers.”
Pratt signed the documents last week on Aug. 13, which will make the former reality TV stars’ divorce final six months from that date – on Valentine’s Day.
Montag filed for divorce on July 30, citing irreconcilable differences.
