Holly Madison is set to tie the knot!

The former Playboy Playmate, 33, announced that her boyfriend Pasquale Rotella popped the big question on her official blog.

"I got engaged on Sunday!" she wrote on her Celebuzz page. "My fiance was so wonderful in creating such a romantic night! He proposed to me at the top of the Ferris wheel at EDC (Electric Daisy Carnival) Las Vegas. I was so happy that so many of our close friends were there to share the wonderful moment with us!"

Rotella is a 38-year-old party promoter and the CEO and founder of Insomniac events -- which puts on the Electric Daisy Carnival. The festival is an "experience-based" event that is known for its colorful costumes, music and fireworks. The event is mainly geared toward electric dance music fans and occurs once a year, according to the website.

"We rode around the festival on the art car until the sun came up!" she continued. "I couldn't have asked for a more wonderful or magical proposal! And a big thank you to Denise Truscello for capturing every moment of this very special night!!" (See photos above)

The pair welcomed their daughter, Rainbow Aurora Rotella, on Tuesday, March 5. Madison explained why she chose the unique name, saying: "Growing up, there was a girl in my school named Rainbow and I was so envious of that name -- I thought it was so pretty and unique!"

Rotella and Madison had been dating for over a year before she announced her pregnancy in August.

The former "Girls Next Door" star, who recently appeared in the highly-acclaimed Las Vegas burlesque show "Peepshow," kept her fans updated on her official website about her experience as a new mom.

"Hi everyone! I just wanted to say thank you for all the wonderful messages you guys have been posting! I appreciate them all," she wrote in March. "I've been spending the last day or so learning how to be a mom -- it's the best project in the world! I never thought I would be so happy -- especially on so little sleep!"
