Salma Hayek proved she had a very eventful 55th birthday with her latest Instagram video! The actress was surrounded by family and friends, including fellow star Angelina Jolie, 46, while sitting in front of her birthday cake, in a clip she posted on Sept. 3. The guests were all shouting “Mordida!” before she put her face in the cake to take the first bite, which is a tradition Mexicans take part in during birthday celebrations.
