Oscars 2015: Family Members Are the Oscars Accessory Du Jour

Dakota Johnson and Melanie Griffith

The family that hits up the Oscars together, stays together.

Moms, dads, sibs and progeny are the popular plus-ones at this year's Oscar awards, as Hollywood’s dynastic families (and regular nominated Joe's alike) hit the red carpet together on Sunday, including best supporting actress nominee Patricia Arquette (whose guests included her daughter and siblings Rosanna and Richmond Arquette), presenter Dakota Johnson (who showed up with mom Melanie Griffith — and also totally snapped at her on the carpet) and best supporting actress nom Laura Dern (bringing her children and famous dad, Bruce).

Best actor nominee Michael Keaton had son Sean Douglas in tow — again. While presenter Sienna Miller showed up with dad EdwinAnsel Elgort also got in on the familial fun, bringing mom Grethe Barrett Holby.

Everyone's favorite Brit Benedict Cumberbatch (well, ours at least) came with both parents on his arm. Birdman's Emma Stone (nominated for best supporting actress) also kept it in the family tree, bringing mom Krista, who's advice to her daughter was to "just enjoy the moment." As they say, mama knows best.
