One of the most talked-about unions in Hollywood is officially coming to an end. Spencer Pratt and Heidi Montag are moving forward with their divorce, PEOPLE reports. Pratt's divorce papers were filed in the Santa Monica, California courthouse Thursday afternoon, Montag's lawyer Jodeane Ferrel confirms to the magazine.

"Spencer has acknowledged that the divorce is going forward," Farrell said. "He signed the papers."

In fact, Pratt signed the divorce papers last week on August 13; the divorce will be final in six months, coincidentally on February 14, 2011. Montag filed for divorce from her publicity-loving husband on July 30 just two months after legally separating from Pratt.

"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, said in July. "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."
