Magic Mike hunk Manganiello proposed to the Colombian stunner in December (14) and they gathered family and friends for a private dinner at Soho House on Friday to mark the occasion.

Schwarzenegger was among the guests at the bash and Vergara's 21-year-old son, Manolo, shared photos on Instagram.com of the Terminator star giving a speech at the meal.

He also poked fun at his mother and her husband-to-be's looks, captioning the shot, "Congratulations to these two ugly people. It's so sad, but luckily they have me to aspire to, physically."

Manolo is the Modern Family actress' son with her ex-husband, her high school sweetheart Joe Gonzales. The former couple wed when Vergara was 18, but split shortly afterwards.
