Some celebs wanted to share the moment with those closest to them -- so they brought their siblings as their dates to the black tie event, giving them a chance to enjoy the pomp and circumstance of the star-studded gala.
Here are a few stars who made this year's SAG Awards a family affair.
The La La Land actress, who ended up taking home the award for Outstanding Performance by a Female Actor in a Leading Role, was all smiles before the show as she walked the red carpet with her dapper brother, Spencer Stone. The two could not have looked happier as they posed for photos outside the Shrine Auditorium in Los Angeles.
Emma previously brought Spencer along to the Critics' Choice Awards in December, and he served as her date at last year's SAG Awards as well.
The Hidden Figures actress brought along two different Christians to the SAG Awards this year -- an stunning, ivory Christian Dior gown and her younger brother, Christian Dunst. The pair posed for photos on the red carpet, and Dunst even let him hold her Actor backstage after Hidden Figureswon the award for Outstanding Performance by a Cast.
The Big Bang Theory star brought her younger sister, actress and singer Briana Cuoco, and the pair absolutely ruled the red carpet. Kaley rocked a pale pink, shimmering Marchesa gown with floral embellishments, while Brianna stood out in a form-fitting black dress with a lacy top and half-sleeves.
Briana also served as Kaley's date to last year's SAG Awards, where they looked equally striking on the red carpet.
The teenage Modern Family star -- who dressed to the nines in a black tuxedo with blue paisley tie -- brought along his older sister, Disney Channel star Raini Rodriguez, who dazzled in a shimmering black and royal blue gown.
Aside from family reunions, the big night was also filled with some epic cast reunions! Check out the video below for a look at how some of the stars of your favorite films reconnected at this year's show.
