The Hills’ Spencer Pratt and Heidi Montag have reportedly tied the knot in Cabo San Lucas, Mexico. If that's true, Stephanie Pratt tells In Touch exclusively, “I am not surprised! I knew they would, and Cabo is definitely where they would do it.” But Spencer’s little sister wants the couple to come back and celebrate here in the States. “I hope they come home, though. Spencer always has said he wants to live there.” Heidi, 22, and Spencer, 25, eloped on November 20 on the beach at the One & Only Palmilla resort just outside of Cabo San Lucas.
