Skeptics, take notice: This breakup is for real.
Almost two months after Heidi Montag went to court seeking legal separation from husband Spencer Pratt, the reality starlet filed for divorce.
Montag, 23, cites the usual irreconcilable differences in the divorce petition filed in Santa Monica, Calif., Superior Court.
“Heidi has amended her petition for separation and today has filed a petition for dissolution of marriage from Spencer Pratt,” Montag’s lawyer Jodeane Farrell tells PEOPLE. “The couple has agreed they would like their divorce to be finalized in a timely manner in an out of court settlement. Both parties are amicable with each other and over the possibility of finalizing their divorce.”
