Madison, 33, announced that her boyfriend Pasquale Rotella popped the question on her blog Monday.
"I got engaged on Sunday!" the reality star wrote. "My fiancé was so wonderful in creating such a romantic night! He proposed to me at the top of the ferris wheel at EDC Las Vegas."
She continued, "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!"
The couple welcomed daughter Rainbow Aurora in March but are already planning on expanding their family.
Madison – who documented on pregnancy with Holly Has a Baby – told PEOPLE in May that she and Rotella want "a huge family, like a Kardashian-sized family."
"I want to have three, then wait a few years for them to be older, then have another three," she said.
