The Hills couple were spotted at the Beverly Hills Courthouse on Wednesday, as reports suggested the couple were going to collect their marriage license.
Pratt and Montag got engaged in May 2007, despite rumours they had split.
The couple have also previously called off wedding plans in December 2008 as Heidi was: “not happy with the arrangements.”
It seems Heidi is satisfied this time around, as the couple will be having their rehearsal dinner tonight in Beverly Hills (of course!)
Heidi had a rather public falling out with fellow Hills star, Lauren Conrad after reports suggested the pair had a disagreement about Montag’s relationship with Pratt.
We’re not sure if Conrad will be at the wedding but it’s pretty certain the MTV cameras will be there to follow the ceremony!
