The Hills star Heidi Montag filed for divorce from Spencer Pratt on Friday due to "irreconcilable differences."
The news comes two months after she sought a legal separation from her estranged husband.
People website quoted Heidi's lawyer, Jodeane Farrell, as saying: "Heidi has amended her petition for separation and today has filed a petition for dissolution of marriage from Spencer Pratt.
"The couple has agreed they would like their divorce to be finalised in a timely manner in an out of court settlement. Both parties are amicable with each other and over the possibility of finalising their divorce."
Reality starlet Heidi, 23, married Spencer, 26 in Mexico in 2008, but amid claims that the ceremony was not legal, the pair exchanged vows again in April 2009 in Pasadena, California.
