Lupita Nyong'o made yet another flawless red carpet appearance, this time at the Women in Film Pre-Oscar Cocktail Party in LA on Friday night. The actress was accompanied by her adorable mom, Dorothy, and posed for photos with Helen Mirren, June Squibb, and producer Cathy Schulman. Helen Mirren seemed especially taken with Lupita while holding hands and chatting it up before heading inside the event. Lupita, who is up for the best supporting actress award at the Oscars on Sunday, has been handling her first award season like a pro — not only has she been graciously accepting praise and accolades for her gripping performance in 12 Years a Slave, but she's also been inspiring us along the way. Earlier this week, she took the stage at the Essence Black Women in Hollywood Luncheon and made a moving speech about inner beauty and past struggles with her dark complexion. As we kick off Lupita's big Oscars weekend, keep reading for more photos of her at the Women in Film party.
