Heidi Montag and Spencer Pratt are going to be parents! The Hills couple, who tied the knot in Mexico in 2008 and again on the reality show in 2009, are expecting their first child, Us Weekly confirms. "I have never been more excited," Heidi told the magazine. "The reality is sinking in that we are going to have a child!" And they aren't the only Hills alums expecting. Lauren Conrad, who had a famous feud with the couple on the series, is also pregnant. While there is no word on the sex of Heidi and Spencer's baby yet, their newborn's due date is Oct. 19. Congrats to the pair!
