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.”
The public and Montag’s own former costars from The Hills initially expressed doubts about whether the split was legitimate or another publicity stunt.
They were married last April at a church in Pasadena, Calif., and have been busy ever since.
Montag underwent 10 plastic surgery procedures in one day this year. She followed that by firing Pratt as her manager and beginning her quest to become a big screen actress, filming a role in Adam Sandler’s Just Go With It, and also working on her music career.
Just recently, Pratt, 26, admitted to choosing fame over his wife telling PEOPLE, “We love each other but I’m a fame whore and I’ll never grow out of it. [Heidi] knows that and doesn’t want that.”
