Heidi Montag’s mom isn’t pleased with the 22-year-old daughter’s “symbolic marriage” to Spencer Pratt in Mexico last month. Darlene Egelhoff, 46, even suggests the reality television personality may have drugged Heidi into the elopement.

Mom’s giving the union six months. Hey, that’s longer than most of Pamela Anderson’s marriages have lasted.

“He’s manipulative and seems to have power over Heidi,” Darlene tells Us Weekly. “I would like to see a blood test from Mexico. It wouldn’t surprise me if he had her drugged.”
