Age is just a number for Salma Hayek and Julia Roberts. The 57-year-old and 55-year-old actresses looked stunning while attending the Gala in the Garden event at the Hammer Museum in LA on Saturday. Defying expectations placed on women over 50 in Hollywood, Salma and Julia proved their star power is as vibrant as ever.

Julia dazzled in a black lace mini dress with vibrant orange and teal accents. She paired the sultry number with a menswear-inspired blazer, black pumps and orange earrings. With her highlighted hair in an updo, Julia epitomized glamour and boldness.
