Holly Madison and Her Baby Daddy Take the Next Step

Holly Madison might already have a beautiful daughter Rainbow Aurora Rotella with her music festival producer beau Pasquale Rotella, but it seems he's finally decided that it's time to put a ring on it.

While the two were seen picking out a ring at the end of the former "Girl Next Door" star's E! reality special, "Holly Has a Baby," they hadn't formally decided to take the next step in their relationship until this weekend.

Rotella popped the question to the former Playboy Playmate on Sunday during the Electric Daisy Carnival in Las Vegas and made sure to capture every moment. The couple was so overjoyed about their engagement that they shared the intimate details via Instagram Monday morning.

Thx to those headliners who celebrated with us on and next to the art car till 6:30am," the groom-to-be wrote, to which Holly responded, "Thank you @pasqualerotella for the most special night of my life! I can't wait to be your wife."
