Newlyweds Spencer Pratt and Heidi Montag are upset with the drunken behaviour of the bride's mother and sister at their pre-wedding rehearsal dinner.
The couple, who exchanged vows on Saturday (25Apr09), has revealed that the two Montags embarrassed the wedding party with comments they made over dinner.
Pratt says, "There was a little something... Her sister and her mom did something that I didn't think was very appropriate for a rehearsal dinner... Alcohol and weddings just are not supposed to mix (sic)."
And his new wife insists her family's bad behaviour wasn't limited to the pre-wedding celebrations: "They were very out of line this weekend."
But the Pratts are refusing to go into details, insisting all will be revealed when the wedding footage is aired on an upcoming episode of their reality TV show The Hills.
Phoning in from a pre-honeymoon break in Mexico on Tuesday (28Apr09), Pratt teased Los Angeles radio DJ Ryan Seacrest, stating, "Tune in. We'll just say (at) the rehearsal dinner, some manners were... There's something going on that shouldn't be."
