Jessica Alba's the pretty pregnant woman we've ever seen! Okay, so there are lots of pretty ones, but isn't Jess particularly stunning?!

The actress/entrepreneur attended Lyft's Community Holiday Fiesta Sunday with daughters Haven, 9; Honor, 6, and hubby Cash Warren. Jessica was radiant in a grey slip dress with a cranberry-colored long cardigan sweater. Her daughters were in the holiday spirit, too -- Honor rocking a sequined skirt and Haven in a full white shirt with red bomber jacket. Cash went along with the theme, wearing a holiday-colored plaid and bright red sneakers. Picture perfect!

Alba is expecting the couple's third child in January so this promises to be a very merry and very busy Christmas and holiday season for the family ... congrats!
