Kids grow up so fast these days and no one knows that better than Ana Ortiz. The Devious Maids star, who celebrated her daughter Paloma Louise's 4th birthday on Saturday, tells us that time flies when you're having fun being a mom.

"I can hardly believe it!" Ortiz said of Paloma turning 4. "People always tell you 'it goes by so quickly!' But until you're in it, you have no idea," she said.

To celebrate Paloma's cumpleaños, Ortiz and her husband (musician Noah Lebenzon) invited a few of their daughter's friends to their house for a fairies and dragons party.

"She's super into fairies right now and all of that fantasy princess stuff," said Ortiz, who said the party also included cake and a bouncy house.

Ortiz added that Paloma is not only her "pride and joy," but also "the BEST big sister ever," to her 2-year-old brother, Rafael (he's the adorable cutie wearing the "Puerto Rico" T-shirt!).

Seriously, these kids can't get ANY cuter! Happy birthday, Paloma!
