Tori Spelling shared how her and ex Dean McDermott’s son Liam, 17, turned their family’s Elf on a Shelf display into a “porn massacre” featuring some NSFW poses.

Spelling said Liam again set up the elves in an inappropriate formation later on. “The elves were all in a circle [surrounding reindeer] and I was like, ‘Oh, man, Liam, you’re a jerk,’” she recalled. Spelling shares her five kids with her ex-husband, Dean McDermott.

The actress says she and her four older kids share the duty of setting up the festive toys for her 7-year-old son Beau

The elves were all doing various things to each other. Mouths on different areas, mouths where they shouldn’t be,” the actress recalled.
