"I got engaged on Sunday!" the former Playboy model wrote Monday. "My fiance was so wonderful in creating such a romantic night! He proposed to me at the top of the Ferris wheel at EDC Las Vegas."
"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 cart until the sun came up! I couldn't have asked for a more wonderful or magical proposal," she added.
The couple's daughter Rainbow Aurora was born in March, People.com said.
