While the Buffy the Vampire Slayer alum walked the red carpet alone before joining some of her A-list co-stars, including Riverdale's Camila Mendes and Stranger Things' Maya Hawke,
She later posed for a rare photo with her daughter, whom she shares with her husband Freddie Prinze Jr. The couple are also parents to a 10-year-old son, Rocky Prinze.
The photo stoked fan interest, as the I Know What You Did Last Summer actress has shielded her children from the public eye to a great extent,
even covering them with emojis over their faces when she posts family photos on Instagram. The 38-year-old actress looked chic in a black dress and wore her long blonde hair down.
For the screening, Gellar rocked a bronze sequin dress and neutral makeup, whereas her daughter who air kissed her on the cheek in a cute snap
opted for a lively hot pink blazer with matching slacks and bright eye makeup, along with white kicks.
The 45-year-old has taken on a mentoring role with her co-stars by sharing a few pics on social media with the caption, "Revenge mommies and their preggy babies."
