Holly Madison is engaged

There's one less bunny on the loose.

Hugh Hefner's ex, Playboy model Holly Madison, has announced on a blog that she is engaged to her boyfriend, event planner Pasquale Rotella.

Madison, 33, gave birth to baby girl Rainbow three months ago, and now her boyfriend has made things official in an apparent romantic Sin City proposal on Sunday.

"He proposed to me at the top of the Ferris wheel at EDC (Electric Daisy Carnival) Las Vegas," wrote the 33-year-old Madison. "I was so happy that so many of our close friends were there to share the wonderful moment with us! We rode around the festival on the art car until the sun came up! I couldn't have asked for a more wonderful or magical proposal!"
