BBFs (big-breasted friends) Salma Hayek and Susan Sarandon attended the "Women In Motion" Prize reception in Cannes on May 15, along with some of their greatest accessories: their boobs. Way too long after the two stars appeared in their equally boob-tastic dresses, Hayek posted a picture to Instagram of the two comparing racks. 

Salma: "Susan, you are bigger than me!" Susan Sarandon: "Of course I am..." #cannes #friends #susansarandon

From left to right, those breasts are 49, 49, 69, and 69 years old. They've aged well.

Susan Sarandon has done an excellent job of late at dressing her breasts.
