The Speidi split now has a paper trail.
The 23-year-old “Hills” star cited irreconcilable differences for the split, but did not check a box for divorce.
That means Montag’s earnings will become her own property from Tuesday, the date Montag filed for separation, TMZ reported.
Montag and Pratt wed in April 2009 and went on to co-author the tome "How to be Famous."
“There are so many lies out there about me and I just needed space – even away from my husband," Montag told People.
Fellow “Hills” castmates have said they believe the breakup is a publicity stunt.
"I think it's a joke," Audrina Patridge told People.com at the MTV Movie Awards on Sunday. "I don't believe it. They're inseparable and in love."
Reps for Montag and Pratt have not commented on the latest developments.
