HEIDI Montag and the FULL BODY WAX - defiantly more than I wanted to KNOW!!

Heidi Montag may have her very own clothing collection, but that doesn't mean that "The Hills" hottie necessarily has the most appropriate sense of style.Montag surprised staffers at West Hollywood's Ona Spa last weekend when she strolled in wearing a see-through sundress and insisted on a full body wax.We're told that halfway through "going bare," Heidi started talking somewhat loudly about her overbearing love for (annoying) boyfriend Spencer Pratt."I wanted to vomit," an ear witness told Pop Tarts.But they must be paying those reality kids pretty well these days, as the blonde babe apparently left a "very generous" tip. Well, it's either that or Montag was making up for the negative press she received last week when it was reported by TMZ that she and Pratt only left $16 on a $783 dinner bill at an L.A. restaurant, prompting one of the show's (embarrassed) producers to step in and leave some cash from his personal pocket.
