Milani was a model on NBC's prime-time game show "Deal or No Deal" from 2005 to 2009. She was best known for her "lioness-like" mane, and held case #13 since the beginning of the show. Although 13 is usually considered the unluckiest of numbers, she was often referred to on the show as "Lucky Leyla" or "Lucky 13," as many times her case contained 6 digit amounts and in eight instances contained the $1,000,000 top prize. Nonetheless, NBC once opened the show noting that by holding all the large amounts and not being picked at the beginning, case #13 was very unlucky during most of the first season. On at least one occasion during the second season, case #13 contained a seven-figure prize.
