The family of missing fashion mogul Vittorio Missoni has been given a boost after his disappearance - his niece Margherita Missoni is reportedly pregnant.

The 30-year-old heiress, who is the accessories director at her family's company, debuted a noticeable baby bump during Paris Fashion Week (05Mar13).

The former model has not yet confirmed the news, but she appeared to be several months along and flaunted her new shape by posing for photos cradling her belly.

Margherita married racing driver Eugenio Amos in her hometown of Brunello, Italy, last June (12).

The Missoni family is still searching for Vittorio, the 58-year-old co-owner of the famed label, after his plane disappeared off the coast of Venezuela on 4 January (13).
